Procedures

ophthalmology

Cataract surgery, also called lens replacement surgery, is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. The eye's natural lens is usually replaced with an artificial intraocular lens (IOL) implant.

ophthalmology

Glaucoma surgery is a type of eye surgery performed to treat glaucoma, a group of diseases which affect the optic nerve, resulting in vision loss. Glaucoma is characterized by increased intraocular pressure (IOP).

ophthalmology

LASIK (Laser-Assisted In Situ Keratomileusis) reshapes the cornea using an excimer laser to correct refractive errors including myopia, hyperopia, and astigmatism. A thin corneal flap is created, the underlying tissue is reshaped, and the flap is repositioned. The procedure takes approximately 15 minutes per eye with rapid visual recovery.

ophthalmology

An intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as near-sightedness (myopia) and far-sightedness (hyperopia); a form of refractive surgery. If the natural lens is left in the eye, the IOL is known as phakic, otherwise it is a pseudophakic lens.

ophthalmology

PRK is a refractive laser eye surgery in which the corneal epithelium is removed and an excimer laser reshapes the underlying corneal stroma to correct myopia, hyperopia, or astigmatism. PRK predates LASIK and remains the preferred surface-ablation technique for patients with thin corneas, occupational requirements that contraindicate a corneal flap (military, contact sports), or borderline topography that makes a flap risky. Recovery is slower and more uncomfortable than LASIK because the epithelium has to heal over the treated cornea — typically 3-5 days with a bandage contact lens — but biomechanical integrity of the cornea is preserved.

ophthalmology

Clear lens extraction, also known as refractive lensectomy, custom lens replacement or refractive lens exchange is a surgical procedure in which clear lens of the human eye is removed. Unlike cataract surgery, where the cloudy lens is removed to treat a cataract, clear lens extraction is done to surgically correct refractive errors such as high myopia.

ophthalmology

Eye surgery, also known as ophthalmic surgery or ocular surgery, is surgery performed on the eye or its adnexa. Eye surgery is part of ophthalmology and is performed by an ophthalmologist or eye surgeon.

ophthalmology

SMILE is a refractive laser eye procedure in which a femtosecond laser creates a small lens-shaped piece of corneal tissue (a lenticule) within the intact cornea, which is then extracted through a small peripheral incision typically 2-4mm wide. Because no corneal flap is created, SMILE preserves more of the cornea's anterior biomechanical strength than LASIK. SMILE is approved for the correction of myopia and myopic astigmatism; hyperopic SMILE has been approved in some markets more recently.
