laser iridotomy
It is used only after medications and laser trabeculoplasty (less invasive procedure that uses a laser to open the blocked trabeculum) have failed to alleviate the pressure.
Laser Trabeculoplasty
Laser peripheral iridotomy makes an opening in the iris allowing the fluid to drain, argon laser trabeculoplasty is aimed at the fluid channel opening to help the drainage system function.
Laser retinopexy is the term for reattaching a detached retina using laser therapy. This procedure involves using a laser to create burns around the retinal tear to seal it and prevent further detachment.
SLT (Selective Laser Trabeculoplasty) Polychromasia refers to a rare phenomenon observed in the context of glaucoma treatment. It involves the appearance of multiple colors in the trabecular meshwork of the eye after SLT, a laser procedure used to lower intraocular pressure. This coloration is attributed to the dispersion of pigment within the trabecular meshwork, which can occur as a result of the laser's interaction with the tissue. While generally not harmful, it can be an interesting clinical observation for ophthalmologists.
Several types of glaucoma can be treated with laser surgery, depending on the specific characteristics of the condition and the individual's response to other treatments. The types of glaucoma that are commonly treated with laser surgery include: Open-Angle Glaucoma: This is the most common type of glaucoma, characterized by increased intraocular pressure (IOP) due to the slow drainage of aqueous humour from the eye's drainage angle. Laser trabeculoplasty, such as selective laser trabeculoplasty (SLT) or argon laser trabeculoplasty (ALT), can be used to improve drainage and lower IOP. Angle-Closure Glaucoma (Narrow-Angle or Closed-Angle): In angle-closure glaucoma, the drainage angle of the eye becomes blocked or narrowed, leading to a rapid increase in IOP. Laser peripheral iridotomy (LPI) is a common procedure used to create a small hole in the iris, allowing fluid to flow freely and relieve the angle closure. Secondary Glaucomas: These are glaucomas that occur as a result of other eye conditions or systemic diseases. Laser surgery may be used as part of the treatment for certain secondary glaucomas, such as neovascular glaucoma or pigmentary glaucoma. Progressive Glaucomas: In some cases, laser surgery may be recommended for progressive glaucomas that are not adequately controlled with medications or other treatments. This may include repeat laser treatments or combined procedures. It's important to note that the suitability of laser surgery for treating glaucoma depends on factors such as the type and severity of glaucoma, the presence of other eye conditions, and the individual's overall eye health. A comprehensive eye examination and consultation with an ophthalmologist are necessary to determine the most appropriate treatment approach for each person with glaucoma.
Using the SLT beam instead of the YAG beam for a posterior capsulotomy may not be effective. The YAG laser has higher energy levels and is specifically designed for creating the necessary opening in the posterior capsule. The SLT laser, typically used for trabeculoplasty, may not have the power to achieve the desired outcome for a posterior capsulotomy.

The old laser printers used He-Ne laser , and the modern laser printers use infrared laser .
Laser pointers and laser pens are basically the same thing. A laser pen is a laser pointer with a pen attached.
