Cataract surgery is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification, which is referred to as a cataract. Metabolic changes of the crystalline lens fibers over time lead to the development of the cataract and loss of transparency, causing impairment or loss of vision. Many patients' first symptoms are strong glare from lights and small light sources at night, along with reduced acuity at low light levels. During cataract surgery, a patient's cloudy natural cataract lens is removed and replaced with a synthetic lens to restore the lens's transparency.
Vitreoretinal (retina) specialists are ophthalmologists specializing in treatment of all retina diseases including age-related macular degeneration, retinal detachment, macular holes, and diabetic retinopathy. Following medical school, these physicians complete a three-residency followed by a two-year fellowship in vitreoretinal diseases and surgery.
Strabismus surgery (also: extraocular muscle surgery, eye muscle surgery, or eye alignment surgery) is surgery on theextraocular muscles to correct the misalignment of the eyes. With approximately 1.2 million procedures each year, extraocular muscle surgery is the third most common eye surgery in the United States.
Corneal cross-linking (CXL) is an in-office eye procedure that strengthens the cornea if it's been weakened by keratoconus, other corneal disease. Alternative and brand names for the procedure include corneal crosslinking, corneal collagen crosslinking, C3-R, CCL and KXL.
The minimally invasive CXL procedure involves applying liquid riboflavin (vitamin B2) to the surface of the eye, followed by treatment with a controlled application of ultraviolet light, to eliminate corneal ectasia.
The two basic types of corneal cross-linking are:
Corneal crosslinking also can be combined with other procedures for keratoconus treatment. For example, combining CXL with implanting tiny arc-shaped corneal inserts called Intacs has been shown to help reshape and stabilize the cornea in more advanced cases of keratoconus.
Toronto—Endonasal dacryocystorhinostomy (DCR) is quickly becoming an attractive procedure among ophthalmologists, according to Nancy Tucker, MD.
The interest in endonasal DCR has been increasing due to the procedure:
· Avoiding a visible incision and wound-related complications
· Having no postoperative bruising or swelling
· Offering minimal to no patient discomfort
· Providing more rapid recovery postoperatively.
The procedure is also safe—even in cases of acute dacryocystitis—and it can be used for DCR with Jones tubes, said Dr. Tucker, Department of Ophthalmology and Vision Sciences, University of Toronto.
All glaucoma surgery procedures (whether laser or non-laser) are designed to accomplish one of two basic results: decrease the production of intraocular fluid (aqueous humor) or increase the outflow (drainage) of this same fluid. Occasionally, a procedure will accomplish both.
Currently the goal of glaucoma surgery and other glaucoma treatment is to reduce or stabilizeintraocular pressure (IOP). When this goal is accomplished, damage to ocular structures — especially theoptic nerve — may be prevented.
Avastin is part of a class of drugs that block the growth of abnormal blood vessels, which is the cause of wet age-related macular degeneration (AMD). Avastin is also used in some cases to treat macular edema, or swelling of the macula, often associated with diabetic retinopathy.
Avastin was initially approved by the Food and Drug Administration (FDA) as a treatment for different types of cancer. Its use to treat eye disease is considered an “off-label” use. The FDA allows the use of drugs for conditions other than those for which it is approved if doctors are well informed about the product and proof has been shown of the drug’s positive effects.
Another drug, Lucentis® (ranibizumab), is chemically similar to Avastin and has been approved by the FDA to treat wet AMD. Based on a study funded by the National Eye Institute (NEI), a part of the federal National Institutes of Health (NIH), the two drugs have equal effect on visual acuity.
Vision correction benefits designed to delight you.
Many vision correction procedures promise an improved level of vision, but few vision correction alternatives offer the quality and features found with the ICL. Namely:Does not induce dry eye syndrome; Sharp, Clear Vision with
Abbreviation standing for laser-assisted in situkeratomileusis, a kind of laser eye surgery designed to change the shape of the cornea to eliminate or reduce the need for glasses and contact lenses in cases of myopia, hyperopia, astigmatism. With PRK, the corneal epithelium is removed and discarded, allowing the cells to regenerate after the surgery.
