What is the most common type of cataract surgery?
The most common type of cataract surgery is phacoemulsification. This modern procedure involves the use of an ultrasonic device to emulsify and remove the cloudy lens inside the eye, which is the cataract. Here's a step-by-step overview of the procedure: *Anesthesia*: Typically, local anesthesia is used to numb the eye, ensuring the patient feels no pain during the surgery. Sedatives may also be administered to help the patient relax. *Corneal Incision*: The surgeon makes a small incision in the cornea, the clear, dome-shaped surface that covers the front of the eye. *Capsulorhexis*: A small, circular opening is made in the capsule (the membrane that encloses the lens) to access the cataract. *Phacoemulsification*: An ultrasonic probe is inserted through the corneal incision into the capsule. This probe vibrates at an ultrasonic frequency to break up the cloudy lens into small pieces. *Aspiration*: The emulsified pieces of the lens are then gently suctioned out of the eye. *Lens Implantation*: After the natural lens has been removed, it is replaced with an artificial intraocular lens (IOL). The IOL is folded and inserted through the original incision, then it unfolds once in place. *Closure*: Typically, the incisions are small enough to heal without sutures, sealing themselves naturally. This procedure typically takes about 30 minutes and is generally safe and effective, offering rapid recovery of vision for most patients. Alternative techniques, such as extracapsular cataract extraction (ECCE) or intracapsular cataract extraction (ICCE), are less commonly used today due to the effectiveness and reduced recovery time associated with phacoemulsification.
After what type of cataract extraction can another cataract later form?
If an extracapsular cataract extraction was performed, a secondary cataract may develop in the remaining back portion of the capsule.
What type of nitroglycerin is good at preventing angina?
nitroglycerin tablets or nitroglycerin spray can both be applied sublingually (under the tongue). Either of these methods are the best type to prevent angina Pectoris

What is the most prevalent type of cataract?
A cataract is the clouding of the lens in the eye preventing normal vision by restricting light passage through the lens. The most common type of cataract due to unprotected exposure to sun rays is nuclear cataracts. Cataract affect people usually as they age due to the changes in the proteins in the lens.
Which procedure is the removal of a cataract leaving the posterior lens capsule intact?
YAG capsulotomy is most often used for this type of cataract.
What is phacoemulsification cataract surgery?
Phacoemulsification cataract surgery is a procedure in which an ultrasonic device is used to break up and then remove a cloudy lens, or cataract, from the eye to improve vision. The insertion of an intraocular lens (IOL) usually immediately follows
What is the most effective angina treatment?

Why all terms are words but not all words are terms?

What is Femto Laser-Assisted Cataract Surgery?
Femto laser-assisted cataract surgery is a new and innovative way to perform cataract surgery. It uses a special type of laser to create precise incisions in the eye, which allows the surgeon to remove the cataract with greater accuracy and efficiency. During the surgery, the surgeon first creates a tiny opening in the eye using the laser. They then use the laser to soften the cataract, which makes it easier to remove. Finally, they use a special tool to remove the cataract and replace it with an artificial lens.
Should a person with angina avoid strenuous exercises like jogging?
angina is a clinical diagnosis, & investigations are usually not very helpful in reaching a diagnosis of angina. angina is defined as a feeling of chest pain or discomfort, especially a squeezing or a constricting type of pain over your chest or other parts of body , usually radiating to left arm & shoulder, aggravated on physical activity or mental stress, which may or may not e relieved by rest.
What causes PSC cataracts?
located within the rear surface of the lens. This common type of cataract occurs in the elderly as "senile cataract" or at any age after chronic intraocular inflammations or prolonged steroid drug use.
