How does LASIK surgery affect cataract surgery?

User Avatar

Asked by Zoso967

If someone has already had successful cataract surgery and requires LASIK to improve myopia (nearsightedness), hyperopia (farsightedness) or astigmatism, the LASIK procedure would reshape the front of the cornea and should not adversely affect the prior cataract removal and lens implant surgery if LASIK is done after the eye has completely healed from cataract surgery.

However, for someone who has previously had LASIK and is now considering cataract surgery, it is not so simple. LASIK reshapes the cornea and corneal measurements are used to calculate the intraocular lens used to replace the cataract. Unfortunately, the calculations currently used do not work as well after LASIK (or other refractive surgery). So, anyone who has previously had corneal refractive surgery prior to cataract surgery may need it again after cataract surgery.

For further questions, you should ask your surgeon.

What qualifications do you need to be a pharmacist?

User Avatar

Asked by Wiki User

The following is written by and according to the U.S. Department of Labor.

A license is required in all States and the District of Columbia, as well as in Guam, Puerto Rico, and the U.S. Virgin Islands. In order to obtain a license, pharmacists generally must earn a Doctor of Pharmacy (Pharm.D.) degree from a college of pharmacy and pass several examinations.

Education and training. Pharmacists who are trained in the United States must earn a Pharm.D. degree from an accredited college or school of pharmacy. The Pharm.D. degree has replaced the Bachelor of Pharmacy degree, which is no longer being awarded. To be admitted to a Pharm.D. program, an applicant must have completed at least 2 years of specific professional study. This requirement generally includes courses in mathematics and natural sciences, such as chemistry, biology, and physics, as well as courses in the humanities and social sciences. In addition, most applicants have completed 3 or more years at a college or university before moving on to a Pharm.D. program, although this is not specifically required.

Pharm.D. programs generally take 4 years to complete. The courses offered are designed to teach students about all aspects of drug therapy. In addition, students learn how to communicate with patients and other healthcare providers about drug information and patient care. Students also learn professional ethics, concepts of public health, and business management. In addition to receiving classroom instruction, students in Pharm.D. programs spend time working with licensed pharmacists in a variety of practice settings.

Some Pharm.D. graduates obtain further training through 1-year or 2-year residency programs or fellowships. Pharmacy residencies are postgraduate training programs in pharmacy practice and usually require the completion of a research project. The programs are often mandatory for pharmacists who wish to work in a clinical setting. Pharmacy fellowships are highly individualized programs that are designed to prepare participants to work in a specialized area of pharmacy, such clinical practice or research laboratories. Some pharmacists who own their own pharmacy obtain a master's degree in business administration (MBA). Others may obtain a degree in public administration or public health.

What are the disadvantages and advantages about lasers?

Asked by Wiki User

(Being a Biomedical Student I can Focus on Clinical aspects.)
1. seals blood vessels while cutting any tissue 2. no need to distend with high pressure fluids to stop bleeding - less swelling 3. no need for repetitive diathermy to burn tissues to stop bleeding 4. no need for drainage tubes to drain blood post-operatively (one cause of pain) 1. no need to keep changing instuments through the skin wounds 2. less damage to the portal tissues 3. less likelihood of breaking instruments 4. shorter operating & anaesthetic times as ergonomically more efficient 1. therefore less scuffing to adjacent joint surfaces 2. less damage to surrounding tissues which may be stretched to admit actions of conventional instruments eg. basket forceps 3. better access as fits into very small spaces with gentle curve 1. photo stimulation - some early studies have recognised early ingrowth of healing tissues 1. very easy to manipulate as flexible 2. sensitive to the surgeon - better feel and so may be more delicate 3. works very well in an aqueous medium ie. in a joint with arthroscopy 1. bone sculpting, cartilage contouring now possible 2. therefore training and accreditation of the surgeon most important - in Australia all surgeons who use this should have laser credentialling. 1. once a hospital has a laser the ongoing costs are less than conventional equipment ie. less dispoable "single use" expensive equipment 2. reusable hand pieces (~cost of 1 blade/case) - not adding a lot more expense!

Especially for the patient:1. "less subjective pain; less apparent bleeding and swelling" 1. The surgeon does not need to pump in fluid under pressure to stop the bleeding - this normally causes marked swelling and distention of tissues which is a cause of pain after the traditional arthroscopic surgical operations. 2. tourniquets are not needed and they cause pain because of the period of ischaemia and the pressure beneath 3. no drainage tubes which cause pain with movements 2. reduces surgical time 1. so less problems from the anaesthetic ie. nausea and drowsiness 2. patient gets over the operation more quickly 3. less compliocations from the anaesthetic- important if previous medical problems 3. no charring therefore less irritation and inflammation
4. Safety considerations 1. surface ablation 0.4mm per pulse 2. surrounding tissue effect <1mm. and this seals the blood vessels 3. if beam doesnt come into contact with tissue within 4 mm. a harmless bubble forms as completely absorbed by the fluid - little likely damage to other tissues besides the one being targeted 5. Precise surgery 1. minimal damage/spread other tissues 2. allows better sparing of adjacent tissues - meniscus, labrum 3. safe - danger zone only 3-4mm in water 4. very precise cutter, ablator,coagulator # Lasers are of high price and limited wavelength range. # Relatively few surgeons are trained in laser use. # Laser equipment is expensive and bulky compared with the usual surgical tools, such as scalpels. # Strict safety precautions must be observed in the operating room. (For example, the surgical team and the patient must use eye protection.) Although many laser surgeries can be performed in a doctor's office rather than in a hospital, the person guiding the laser must be at least as thoroughly trained and highly skilled as someone performing the same procedure in a hospital setting. The American Society for Laser Medicine and Surgery, Inc. urges that:

* All operative areas be equipped with oxygen and other drugs and equipment required for cardiopulmonary resuscitation (CPR)

* Non-physicians performing laser procedures be properly trained, licensed, and insured

* A qualified and experienced supervising physician be able to respond to and manage unanticipated events or other emergencies within five minutes of the time they occur

* Emergency transportation to a hospital or other acute-care facility be available whenever laser surgery is performed in a non-hospital setting.

Imprecisely aimed lasers can burn or destroy healthy tissue.

#If laser hair elimination method is not performed properly, it may cause many skin diseases such as discoloration of skin or burning of the skin.

What lasik eye surgery does?

User Avatar

Asked by Wiki User

Basically Lasik is the most popular laser eye surgery that can correct or sometimes even cure common refractive errors like Hyperopia (farsightedness) etc. What Lasik does is create a thin flap on the surface of the cornea w/c is then surgically folded to the side to let laser energy reshape the exposed surface of the cornea. After the procedure, the corneal flap is folded back for rapid recovery. If you want a visual on what I just said you can refer to the related link(Lasik Philippines) I placed below...

Can laser eye surgery fix a lazy eye?

User Avatar

Asked by Wiki User

In general, if you are referring to an eye muscle disorder in which the eye position is not straight, there is no laser for these procedures yet. Most eye muscle surgeries are traditional surgeries in which muscles are moved to new positions on the eye using an operating microscope or mounted loupe spectacles with high magnification. There are no skin incisions and of course the eye is never removed ( a common public concern). Repositioning the eye muscles takes a highly skilled expert in "strabismus" and most of us that do this are also pediatric ophthalmologists.

In children who have amblyopia, or a visually lazy eye, the treatments continue to be glasses and patch therapy. The headlines in today's papers as you may have read concern new intraocular implants that are being researched to treat amblyopia in some children who have one really near or far sighted eye and either cannot wear glasses due to the high difference in power, or will not tolerate a contact lens. Unfortunately such procedures are without a documented track record, and are new. Also none of them are used for adults as the brain and the eye complete almost all visual development by the late teens.

How can you make your lips bigger without any type of surgery or makeup?

User Avatar

Asked by Wiki User

a good way for a temporary plump would be to use a old toothbrush with rustled brushes and exfoliate your lips. cover them with vaseline first and wait for the vaseline to sit before exfoliating. be careful not to do this too hard as your lips are delicate. make sure your lips are NOT CHAPPED and apply moisture thru chapstick or vaseline (not lipstick/gloss!!!)to your lips immediately after exfoliating. lipstick and gloss will dry out your lips even more so you'd have big lips but chapped ones as well. this trick will not only make your lips bigger, but it will give a more reddish and more natural color to your lips as well. (temporary tho of course)

The other alternative is to use a lip plumper. There are several on the market, some of which are better than others. A good one that appears to have a lot of good reviews is http://lusciouslips.org. You will find once it is applied that your lips start tingling, however this is supposed to happen and means the product is working on plumping your lips. With most lip plumpers the results should be immediate or at the most 5 to 10 minutes.

What is the difference between Lasik and PRK?

User Avatar

Asked by Wiki User

LASIK and PRK are both laser procedures that correct nearsightedness, farsightedness, astigmatism and presbyopia. The main difference between the two is the following: LASIK uses a microtome knife or laser to create a flap followed by use of an Eximer laser to ablate the corneal tissues. PRK, on the other hand, uses a sterile brush or laser to scrape away the surface corneal epithelial cells, followed by use an Excimer laser to ablate and reshape the corneal tissue. Although PRK takes longer to heal and produces more discomfort than LASIK, it is an ideal surgery for patients with thin corneas and large pupils. To learn more about PRK and LASIK, send your queries to http://www.about-eyes.com/ or CataractCoach@twitter.com. Thanks for asking.

What company has the cheapest lasik price?

User Avatar

Asked by Wiki User

Most patients are very pleased with the results of their refractive surgery. However, like any other medical procedure, there are risks involved. That's why it is important for you to understand the limitations and possible complications of refractive surgery. Before undergoing a refractive procedure, you should carefully weigh the risks and benefits based on your own personal value system, and try to avoid being influenced by friends that have had the procedure or doctors encouraging you to do so. * Some patients lose vision. Some patients lose lines of vision on the vision chart that cannot be corrected with glasses, contact lenses, or surgery as a result of treatment. * Some patients develop debilitating visual symptoms. Some patients develop glare, halos, and/or double vision that can seriously affect nighttime vision. Even with good vision on the vision chart, some patients do not see as well in situations of low contrast, such as at night or in fog, after treatment as compared to before treatment. * You may be under treated or over treated. Only a certain percent of patients achieve 20/20 vision without glasses or contacts. You may require additional treatment, but additional treatment may not be possible. You may still need glasses or contact lenses after surgery. This may be true even if you only required a very weak prescription before surgery. If you used reading glasses before surgery, you may still need reading glasses after surgery. * Some patients may develop severe dry eye syndrome. As a result of surgery, your eye may not be able to produce enough tears to keep the eye moist and comfortable. Dry eye not only causes discomfort, but can reduce visual quality due to intermittent blurring and other visual symptoms. This condition may be permanent. Intensive drop therapy and use of plugs or other procedures may be required. * Results are generally not as good in patients with very large refractive errors of any type. You should discuss your expectations with your doctor and realize that you may still require glasses or contacts after the surgery. * For some farsighted patients, results may diminish with age. If you are farsighted, the level of improved vision you experience after surgery may decrease with age. This can occur if your manifest refraction (a vision exam with lenses before dilating drops) is very different from your cycloplegic refraction (a vision exam with lenses after dilating drops). * Long-term data are not available. LASIK is a relatively new technology. The first laser was approved for LASIK eye surgery in 1998. Therefore, the long-term safety and effectiveness of LASIK surgery is not known. Additional Risks if you are Considering the Following: * MonovisionMonovision is one clinical technique used to deal with the correction of presbyopia, the gradual loss of the ability of the eye to change focus for close-up tasks that progresses with age. The intent of monovision is for the presbyopic patient to use one eye for distance viewing and one eye for near viewing. This practice was first applied to fit contact lens wearers and more recently to LASIK and other refractive surgeries. With contact lenses, a presbyopic patient has one eye fit with a contact lens to correct distance vision, and the other eye fit with a contact lens to correct near vision. In the same way, with LASIK, a presbyopic patient has one eye operated on to correct the distance vision, and the other operated on to correct the near vision. In other words, the goal of the surgery is for one eye to have vision worse than 20/20, the commonly referred to goal for LASIK surgical correction of distance vision. Since one eye is corrected for distance viewing and the other eye is corrected for near viewing, the two eyes no longer work together. This results in poorer quality vision and a decrease in depth perception. These effects of monovision are most noticeable in low lighting conditions and when performing tasks requiring very sharp vision. Therefore, you may need to wear glasses or contact lenses to fully correct both eyes for distance or near when performing visually demanding tasks, such as driving at night, operating dangerous equipment, or performing occupational tasks requiring very sharp close vision (e.g., reading small print for long periods of time). Many patients cannot get used to having one eye blurred at all times. Therefore, if you are considering monovision with LASIK, make sure you go through a trial period with contact lenses to see if you can tolerate monovision, before having the surgery performed on your eyes. Find out if you pass your state's driver's license requirements with monovision. In addition, you should consider how much your presbyopia is expected to increase in the future. Ask your doctor when you should expect the results of your monovision surgery to no longer be enough for you to see near-by objects clearly without the aid of glasses or contacts, or when a second surgery might be required to further correct your near vision. * Bilateral Simultaneous TreatmentYou may choose to have LASIK surgery on both eyes at the same time or to have surgery on one eye at a time. Although the convenience of having surgery on both eyes on the same day is attractive, this practice is riskier than having two separate surgeries. If you decide to have one eye done at a time, you and your doctor will decide how long to wait before having surgery on the other eye. If both eyes are treated at the same time or before one eye has a chance to fully heal, you and your doctor do not have the advantage of being able to see how the first eye responds to surgery before the second eye is treated. Another disadvantage to having surgery on both eyes at the same time is that the vision in both eyes may be blurred after surgery until the initial healing process is over, rather than being able to rely on clear vision in at least one eye at all times. Finding the Right Doctor

If you are considering refractive surgery, make sure you: * Compare. The levels of risk and benefit vary slightly not only from procedure to procedure, but from device to device depending on the manufacturer, and from surgeon to surgeon depending on their level of experience with a particular procedure. * Don't base your decision simply on cost and don't settle for the first eye center, doctor, or procedure you investigate. Remember that the decisions you make about your eyes and refractive surgery will affect you for the rest of your life. * Be wary of eye centers that advertise, "20/20 vision or your money back" or "package deals." There are never any guarantees in medicine. * Read. It is important for you to read the patient handbook provided to your doctor by the manufacturer of the device used to perform the refractive procedure. Your doctor should provide you with this handbook and be willing to discuss his/her outcomes (successes as well as complications) compared to the results of studies outlined in the handbook. Even the best screened patients under the care of most skilled surgeons can experience serious complications. * During surgery. Malfunction of a device or other error, such as cutting a flap of cornea through and through instead of making a hinge during LASIK surgery, may lead to discontinuation of the procedure or irreversible damage to the eye. * After surgery. Some complications, such as migration of the flap, inflammation or infection, may require another procedure and/or intensive treatment with drops. Even with aggressive therapy, such complications may lead to temporary loss of vision or even irreversible blindness. Under the care of an experienced doctor, carefully screened candidates with reasonable expectations and a clear understanding of the risks and alternatives are likely to be happy with the results of their refractive procedure. Advertising

Be cautious about "slick" advertising and/or deals that sound "too good to be true." Remember, they usually are. There is a lot of competition resulting in a great deal of advertising and bidding for your business. Do your homework. If you want to know more about advertising ethics, do's and don'ts, or want to report on false advertising, explore the following websites: * http://www.ftc.gov/bcp/menu-ads.htm * http://www.ftc.gov/bcp/menu-health.htm Source: http://www.fda.gov/cdrh/lasik/risks.htm
