Treatment: Surgical Removal If there are cataracts in both eyes that require surgery, the surgeries are usually performed several weeks apart. Cataract surgery on both eyes at the same time is not recommended because there is a possibility of complications affecting both eyes; the most worrisome is infection.

The LASIK Procedure: A Complete Guide LASIK, or laser-assisted in situ keratomileusis, is the most commonly performed laser eye surgery to treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. Like other types of refractive surgery, the LASIK procedure reshapes the cornea to enable light entering the eye to be properly focused onto the retina for clearer vision. In most cases, laser eye surgery is pain-free and completed within 15 minutes for both eyes.

- Most types of vision correction surgery 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.Other types involve replacing the eye’s natural lens. AK or RLI: Short for astigmatic keratotomy, this is not laser eye surgery, but a surgical procedure used to correct astigmatism. 2  The cornea of people who have astigmatism is shaped like a football.

A Guide to Refractive and Laser Eye Surgery Vision correction surgery, also called refractive and laser eye surgery, refers to any surgical procedure used to fix vision problems. Recent years have seen huge advances in this field. Refractive and laser eye surgery allow many patients to see better than any other time in their lives. Most types of vision correction surgery reshape your cornea, the clear front part of your eye. That lets light travel through it and focus properly on the back of your eye, or retina.

What Is Refractive Surgery? The most widely performed type of refractive surgery is LASIK (laser-assisted in situ keratomileusis), where a laser is used to reshape the cornea. For people who are nearsighted, certain refractive surgery techniques will reduce the curvature of a cornea that is too steep so that the eye's focusing power is lessened.

Refractive Lens Exchange (RLE) If you wear contact lenses you must stop wearing them prior to surgery–at least two weeks for soft contacts and one month for hard contacts. This is because contact lenses can cause mild warping of the corneal shape, which may interfere with the preoperative measurements of the eye and calculations for RLE surgery.

Refractive Lens Exchange  (Lens Replacement Surgery) Refractive Lens Exchange. (Lens Replacement Surgery) Refractive lens exchange, also called lens replacement surgery or clear lens extraction, may be a better option than LASIK, PRK or phakic IOL refractive surgery for people with presbyopia and high hyperopia (farsightedness).

- A cataract is a painless, cloudy area in the lens of the eye. The lens is enclosed in a lining called the lens capsule. Cataract surgery separates the cataract from the lens capsule. In most cases, the lens will be replaced with an intraocular lens implant (IOL).If an IOL cannot be used, contact lenses or eyeglasses must be worn to compensate for the lack of a natural lens.uring phacoemulsification surgery: 1  Two small incisions are made in the eye where the clear front covering (cornea) meets the white of the eye (sclera). 2  A circular opening is created on the lens surface (capsule). 3  A small surgical instrument (phaco probe) is inserted into the eye.

The Multiple Sides Of Monovision “If patients have used monovision with contact lenses, they’re usually great candidates,” says Deepinder Dhaliwal, MD, director of the cornea and refractive surgery service at the University of Pittsburgh Medical Center. “As presbyopes, it also depends on how particular they are about their vision. If it’s someone who doesn’t do a lot of close work, just reads casually, that type of thing, I think that’s a great candidate.” Dr. Dhaliwal prefers a monovision trial in the phoropter to a contact lens trial in most cases.

- Are there different options for incisions with cataract surgery? In 2012 the FDA approved the first laser designed to be used during cataract surgery. Laser cataract surgery makes very precise incisions in the cornea using laser technology. The laser then makes a perfectly circular opening on the lens surface. The same small ultrasound probe used in regular cataract surgery is then used to liquefy and remove the cloudy cataract lens. Astigmatism treatments can also be performed with a laser (limbal relaxing incisions).

Laser Surgery During the laser surgery, the eye is numbed so that there is little or no pain. The eye doctor then holds a special lens to the eye. The laser beam is aimed into the eye, and there is a bright light, like a camera flash. The following are the most common laser surgeries to treat glaucoma.

Contact Lenses After LASIK Or Other Refractive Surgery Because LASIK and other laser refractive surgery can significantly alter the shape of the cornea, fitting contact lenses on a post-surgery eye is more challenging than fitting lenses on a normally shaped cornea. Special gas permeable or hybrid lens designs usually are required in these circumstances.

Everything You Should Know About Monovision Surgical monovision: The effects of monovision can also be achieved with LASIK (Laser In Situ Keratomileusis) surgery. Instead of using contact lenses, LASIK surgery is used to adjust one eye for focusing on far-away objects, and one eye for focusing on close-up objects.he reverse is true for focusing on objects that are closer. For monovision patients, the dominant eye will be fitted with the contact lens that is suited for driving or other activities that require focusing on objects far away. Closer objects may appear to be blurrier through this eye.

INTACS Other Procedures Intacs. The progression of keratoconus leads to worsening vision, discomfort, and intolerance of contact lenses. For many keratoconus patients, Intacs corneal inserts can be a safe, minimally invasive way to slow or halt that progression.f you are considering Intacs surgery for keratoconus, your first step is to have a comprehensive eye exam by an ophthalmologist who specializes in the procedure.
