Phototherapeutic Keratectomy, or widely known as PTK, is a surgical procedure to treat numerous ocular disorders using an excimer laser. It is one of the latest advances in eye care technology. The procedure is mainly performed to treat diseases that develop on the surface of the cornea or corneal injury. The cornea is the outermost layer of the eye that acts as a window covering the front of the eye. It involves removing a small outer layer of tissue from the cornea. The procedure can treat various corneal dystrophies such as granular dystrophy, recurrent epithelial erosion syndrome (REES), as well as scars on the cornea. This type of surgery is usually performed after other types of treatments
What is vitrectomy?
Vitrectomy is a type of eye surgery to treat various ocular disorders that occur in the retina and vitreous. It involves the removal of the vitreous humor or fluid from the eye. The vitreous is then replaced with another solution. The vitreous is a gel-like fluid made of 98% water that fills the middle part of your eye. The retina is the innermost layer of cells in your eye. These cells are light-sensitive and use light to send visual information to the brain. In normal conditions, the vitreous is clear, so light can pass through the eye and reach the retina. However, certain conditions can cause debris and blood to block this light, which can
Iridectomy is a surgical procedure that is often performed for closed-angle glaucoma. Sometimes called peripheral iridectomy, the procedure involves removing parts of the iris and can be either invasive or less invasive. Less invasive iridectomy uses laser technology, while invasive iridectomy involves incisions.
In this article, we’ll answer some questions about the procedure as well as why it is performed.
What is the purpose of iridectomy?
Iridectomy is mainly performed to treat closed-angle glaucoma, which is a medical condition where the pressure inside your eye becomes too high than its normal pressure. Closed-angle glaucoma is much less common than open-angle glaucoma. In fact, around 90 percent of all glaucoma cases are open-angle glaucoma. People with closed-angle glaucoma experience

LASIK is an acronym for laser in-situ keratomileusis – an operation which helps people suffering from astigmatism. This operation, like all other laser vision correction procedures, is done on the cornea – eye’s front part.
