Lasik & Ophthalmology
Laser in-situ keratomileusis, or LASIK, is a popular surgical approach used to correct vision in people who are nearsighted, farsighted, or have astigmatism.
All laser vision correction surgeries work by reshaping the cornea, or clear front part of the eye, so that light traveling through it is properly focused onto the retina located in the back of the eye. LASIK laser eye surgery (laser in-situ keratomileusis) is one of a number of different surgical techniques used to reshape the cornea.
Pterygium usually refers to a benign growth of the conjunctiva. A pterygium commonly grows from the nasal side of the sclera. It is associated with, and thought to be caused by ultraviolet-light exposure (e.g. sunlight), low humidity, and dust. The predominance of pterygia on the nasal side is possibly a result of the sun's rays passing laterally through the cornea where it undergoes refraction and becomes focused on the limbic area. Sunlight passes unobstructed from the lateral side of the eye, focusing on the medial limbus after passing through the cornea. On the contralateral side, however, the shadow of the nose medially reduces the intensity of sunlight focused on the lateral/temporal limbus.
Eyelid surgery (technically called blepharoplasty) is a procedure to remove fat--usually along with excess skin and muscle from the upper and lower eyelids. Eyelid surgery can correct drooping upper lids and puffy bags below your eyes - features that make you look older and more tired than you feel, and may even interfere with your vision. Blepharolplasty is featured in our plastic and cosmetic surgery section.
