Laser eye surgery

Although the terms laser eye surgery and refractive surgery are commonly used as if they were interchangeable, this is not the case. Lasers may be used to treat nonrefractive conditions (e.g. to seal a retinal tear), while radial keratotomy is an example of refractive surgery without the use of a laser.

Cataract surgery

A cataract is an opacification or cloudiness of the eye's crystalline lens due to aging, disease, or trauma that typically prevents light from forming a clear image on the retina. If visual loss is significant, surgical removal of the lens may be warranted, with lost optical power usually replaced with a plastic intraocular lens (IOL). Due to the high prevalence of cataracts, cataract extraction is the most common eye surgery. Rest after surgery is recommended.

Glaucoma surgery

Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many types of glaucoma surgery, and variations or combinations of those types, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of aqueous humor.

Canaloplasty

Canaloplasty is an advanced, nonpenetrating procedure designed to enhance drainage through the eye’s natural drainage system to provide sustained reduction of IOP. Canaloplasty utilizes microcatheter technology in a simple and minimally invasive procedure.

WHAT IS LASIK?

Laser Assisted Stromal In-situ Keratomileusis [LASIK] is a method of re-shaping the external surface of the eye [the cornea] to correct low, moderate and high degrees of nearsightedness, astigmatism and far-sightedness. During the treatment, an instrument called the microkeratome creates a corneal flap to make it a painless procedure. The computerized Excimer laser then uses a cool beam of light to gently reshape the cornea so as to alter its curvature to the desired extent. The flap when replaced on the new corneal curvature allows images to be sharply focused on the retina. The goal is to eliminate or greatly reduce the dependence on glasses or contact lenses.

Wavefront LASIK

Wavefront-guided LASIK is a promising new technology that provides an advanced method for measuring optical distortions in the eye. Measuring and treating these distortions goes beyond nearsighted, farsighted, and astigmatism determinations that have been used for centuries. As a result, physicians can now customize the LASIK procedure according to each individual patient’s unique vision correction needs. The treatment is unique to each eye, just as a fingerprint is unique. Wavefront systems work by measuring how light is distorted as it passes into the eye and then is reflected back. This creates an optical map of the eye, highlighting individual imperfections.
