Boston Refractive Eye Surgery

Refractive surgery in Boston, and across the globe, should be performed by a surgeon with extensive training and experience. Dr Kornmehl is a leading expert in refractive surgery and laser vision correction. He explains on this webpage how refractive surgery improves vision and whether you should consider this surgery.

What is refractive eye surgery?

Most people are aware that there are new developments in eye surgery intended to reduce dependence on glasses and contact lenses.

Refractive surgery includes several surgical techniques designed to improve problems in focusing the eyes, also known as refractive errors. Until 1989 only glasses or contact lenses could correct refractive problems.

What are refractive problems?

Light is focused, or refracted, by the cornea, the clear front “window” of the eye. Your vision is clear if the cornea and lens combine to focus an image precisely on the retina. The retina is the inner layer of the eye that senses light and helps you to see.

Your vision is blurred if the cornea, lens and eye length place the image in front of the retina. This is known as myopia, or nearsightedness.

Your vision is blurred if the cornea, lens and eye length place the image in back of the retina. This is known as hyperopia, or farsightedness.

If the cornea is not round (like a basketball), but instead has unequal curves (like a football), the image is distorted. This is called astigmatism. An eye with astigmatism may have myopia or hyperopia as well.

Types of Refractive Surgery

Refractive errors such as myopia, hyperopia and astigmatism are solved by helping the eye focus light using glasses, contacts or refractive surgery. Refractive surgery techniques aim to change the eye’s focus by changing the shape of the cornea. Dr. Kornmehl reshapes the cornea by removing tissue using a laser; with a flap (LASIK) or without (PRK). 

LASIK

LASIK (laser in situ keratomileusis) corrects the curvature of your cornea using an FDA-approved excimer laser. The laser is guided by a Wavefront computer system that maps your eye and measures optical distortions. A microkeratome blade or femtosecond laser creates a flap using the cornea’s surface layer and folds it back. The excimer laser removes a thin tissue layer from your cornea to correct your vision, and the flap is replaced — it re-attaches to the cornea with no stitches required in minutes. LASIK treats myopia, hyperopia and astigmatism. 

PRK

Photorefractive keratectomy, or PRK, also uses an excimer laser to reshape the cornea for improved eyesight. Small amounts of tissue are removed from the outer surface of your cornea using a detailed map of your eye’s surface from a computer that calculates the amount of tissue removal precisely. However, PRK does not use a corneal flap. The cornea’s surface layer (epithelium) is removed instead, which requires a bandage contact lens to protect the eye during recovery. PRK treats myopia, hyperopia and astigmatism and may be the better option for someone with severe nearsightedness or thin corneas.

What to Expect During Your Consultation and Preparation for Refractive Surgery

Your consultation will involve a comprehensive eye exam to evaluate your ocular health, eyeglass or contact lens prescription and candidacy for refractive surgery. Dr. Kornmehl may dilate your pupils to reach the most accurate vision measurement and ensure the interior sections of the eye are healthy. Your eyelids may be examined for good tear quality to avoid post-op complications such as dry eyes.

While LASIK is the most common refractive surgery, some people don’t qualify due to thin corneas, severe myopia, dry eye disease or other concerns. PRK may be an alternative option if LASIK isn’t suitable for your vision. However, 30 percent of acceptable LASIK candidates choose to have PRK instead.

You will be asked to prepare for refractive surgery in various ways, including avoiding contact lenses for one or more weeks, depending on the style of contacts you use. You may need to stop taking certain medications or supplements that can interfere with healing. Drink plenty of water to ensure you’re well-hydrated and avoid alcohol the day of your refractive surgery.

Refractive Surgery Recovery

Your recovery will depend on the type of refractive surgery as LASIK and PRK require different healing times. However, you will have blurry vision for several hours after any one of those procedures, so ask a friend or family member to drive you home and help while your vision stabilizes. Many patients can drive themselves to the follow-up appointment the day after refractive surgery.

Dr. Kornmehl will give you detailed instructions for the healing period. When you sleep, you will have to wear protective eyewear to avoid rubbing your eyes for the first week, and prescription and over-the-counter eye drops are necessary to help your eyes heal. Avoid getting water in your eyes for the first week. 

Generally, LASIK recovery is shorter than PRK because the eye must regrow the epithelial layer that is removed during the PRK procedure. LASIK offers faster healing because the flap adheres to your cornea within minutes.

When Will I See Clearly After Refractive Surgery?

LASIK patients notice significant improvement in vision the evening of their surgery. PRK patients notice major improvement in their vision immediately after surgery. Vision will worsen for the next two to three days, then improve rapidly. Your eyesight will continue to improve for six months to a year, but much of the healing process is done after three to six months.
