Laser Eye Surgery (LASIK)

What is LASIK?

For many people, laser eye surgery can correct their vision so they no longer need glasses or contact lenses. Laser eye surgery reshapes the cornea, the clear front part of the eye. This changes its focusing power.

There are different types of laser eye surgery. LASIK - laser-assisted in situ keratomileusis – is one of the most common. Many patients who have LASIK end up with 20/20 vision. But, like all medical procedures, it has both risks and benefits. Only your eye doctor can tell if you are a good candidate for laser eye surgery.

When is LASIK not for me?

You are probably NOT a good candidate for refractive surgery if:

• You are not a risk taker: Certain complications are unavoidable in a percentage of patients, and there are no long-term data available for current procedures.

• It will jeopardize your career: Some jobs prohibit certain refractive procedures. Be sure to check with your employer/professional society/military service before undergoing any procedure.

• Cost is an issue: Most medical insurance will not pay for refractive surgery. Although the cost is coming down, it is still significant.

• You required a change in your contact lens or glasses prescription in the past year. This is called refractive instability. Patients who are:

• In their early 20 or younger, 
• Whose hormones are fluctuating due to disease such as diabetes,
• Who are pregnant or breastfeeding, or 
• Who are taking medications that may cause fluctuations in vision, are more likely to have refractive instability and should discuss the possible additional risks with their doctor.

• You have a disease or are on medications that may affect wound healing. Certain conditions, such as autoimmune diseases (e.g., lupus, rheumatoid arthritis), immunodeficiency states (e.g., HIV) and diabetes, and some medications (e.g., retinoic acid and steroids) may prevent proper healing after a refractive procedure.

• You actively participate in contact sports. You participate in boxing, wrestling, martial arts or other activities in which blows to the face and eyes are a normal occurrence.

• You are not an adult.  Currently, no lasers are approved for LASIK on persons under the age of 18.

What should I expect before, during, and after surgery?

What to expect before, during, and after surgery will vary from doctor to doctor and patient to patient. This is a compilation of patient information developed by manufacturers and healthcare professionals, but cannot replace the dialogue you should have with your doctor. 

Before Surgery

If you decide to go ahead with LASIK surgery, you will need an initial or baseline evaluation by your eye doctor to determine if you are a good candidate. This is what you need to know to prepare for the exam and what you should expect:

If you wear contact lenses, it is a good idea to stop wearing them before your baseline evaluation and switch to wearing your glasses full-time. Contact lenses change the shape of your cornea for up to several weeks after you have stopped using them depending on the type of contact lenses you wear. Not leaving your contact lenses out long enough for your cornea to assume its natural shape before surgery can have negative consequences. These consequences include inaccurate measurements and a poor surgical plan, resulting in poor vision after surgery. These measurements, which determine how much corneal tissue to remove, may need to be repeated at least a week after your initial evaluation and before surgery to make sure they have not changed, especially if you wear RGP or hard lenses. If you wear:

• Soft contact lenses, you should stop wearing them for 2 weeks before your initial evaluation.
• Toric soft lenses or rigid gas permeable (RGP) lenses, you should stop wearing them for at least 3 weeks before your initial evaluation.
• Hard lenses, you should stop wearing them for at least 4 weeks before your initial evaluation.

You should tell your doctor:

• About your past and present medical and eye conditions.
• About all the medications you are taking, including over-the-counter medications and any medications you may be allergic to.

Your doctor should perform a thorough eye exam and discuss:

• Whether you are a good candidate.
• What the risks, benefits, and alternatives of the surgery are.
• What you should expect before, during, and after surgery.
• What your responsibilities will be before, during, and after surgery.

You should have the opportunity to ask your doctor questions during this discussion.  Give yourself plenty of time to think about the risk/benefit discussion, to review any informational literature provided by your doctor, and to have any additional questions answered by your doctor before deciding to go through with surgery and before signing the informed consent form.

You should not feel pressured by your doctor, family, friends, or anyone else to make a decision about having surgery. Carefully consider the pros and cons.

The day before surgery, you should stop using:

• Creams
• Lotions
• Makeup
• Perfumes

These products as well as debris along the eyelashes may increase the risk of infection during and after surgery. Your doctor may ask you to scrub your eyelashes for a period of time before surgery to get rid of residues and debris along the lashes.

Also before surgery, arrange for transportation to and from your surgery and your first follow-up visit. On the day of surgery, your doctor may give you some medicine to make you relax. Because this medicine impairs your ability to drive and because your vision may be blurry, even if you don't drive make sure someone can bring you home after surgery.

During Surgery

The surgery should take less than 30 minutes. You will lie on your back in a reclining chair in an exam room containing the laser system. The laser system includes a large machine with a microscope attached to it and a computer screen.

A numbing drop will be placed in your eye, the area around your eye will be cleaned, and an instrument called a lid speculum will be used to hold your eyelids open. A ring will be placed on your eye and very high pressures will be applied to create suction to the cornea. Your vision will dim while the suction ring is on and you may feel the pressure and experience some discomfort during this part of the procedure. The microkeratome, a cutting instrument, is attached to the suction ring. Your doctor will use the blade of the microkeratome to cut a flap in your cornea. Microkeratome blades are meant to be used only once and then thrown out.

The microkeratome and the suction ring are then removed. You will be able to see, but you will experience fluctuating degrees of blurred vision during the rest of the procedure. The doctor will then lift the flap and fold it back on its hinge, and dry the exposed tissue.

The laser will be positioned over your eye and you will be asked to stare at a light. This is not the laser used to remove tissue from the cornea. This light is to help you keep your eye fixed on one spot once the laser comes on.
NOTE: If you cannot stare at a fixed object for at least 60 seconds, you may not be a good candidate for this surgery.

When your eye is in the correct position, your doctor will start the laser. At this point in the surgery, you may become aware of new sounds and smells. The pulse of the laser makes a ticking sound. As the laser removes corneal tissue, some people have reported a smell similar to burning hair. A computer controls the amount of laser energy delivered to your eye. Before the start of surgery, your doctor will have programmed the computer to vaporize a particular amount of tissue based on the measurements taken at your initial evaluation. After the pulses of laser energy vaporize the corneal tissue, the flap is put back into position.

A shield should be placed over your eye at the end of the procedure as protection, since no stitches are used to hold the flap in place. It is important for you to wear this shield to prevent you from rubbing your eye and putting pressure on your eye while you sleep, and to protect your eye from accidentally being hit or poked until the flap has healed.

After Surgery

Immediately after the procedure, your eye may burn, itch, or feel like there is something in it. You may experience some discomfort, or in some cases, mild pain and your doctor may suggest you take a mild pain reliever. Both your eyes may tear or water. Your vision will probably be hazy or blurry. You will instinctively want to rub your eye, but don't!

Rubbing your eye could dislodge the flap, requiring further treatment. In addition, you may experience sensitivity to light, glare, starbursts or haloes around lights, or the whites of your eye may look red or bloodshot. These symptoms should improve considerably within the first few days after surgery. You should plan on taking a few days off from work until these symptoms subside. You should contact your doctor immediately and not wait for your scheduled visit, if you experience severe pain, or if your vision or other symptoms get worse instead of better.

You should see your doctor within the first 24 to 48 hours after surgery and at regular intervals after that for at least the first six months. At the first postoperative visit, your doctor will remove the eye shield, test your vision, and examine your eye. Your doctor may give you one or more types of eye drops to take at home to help prevent infection and/or inflammation. You may also be advised to use artificial tears to help lubricate the eye. Do not resume wearing a contact lens in the operated eye, even if your vision is blurry.

You should wait one to three days following surgery before beginning any non-contact sports, depending on the amount of activity required, how you feel, and your doctor's instructions.

To help prevent infection, you may need to wait for up to two weeks after surgery or until your doctor advises you otherwise before using lotions, creams, or make-up around the eye. Your doctor may advise you to continue scrubbing your eyelashes for a period of time after surgery. You should also avoid swimming and using hot tubs or whirlpools for 1-2 months.

Strenuous contact sports such as boxing, football, karate, etc. should not be attempted for at least four weeks after surgery. It is important to protect your eyes from anything that might get in them and from being hit or bumped.

During the first few months after surgery, your vision may fluctuate.

• It may take up to three to six months for your vision to stabilize after surgery.
• Glare, haloes, difficulty driving at night, and other visual symptoms may also persist during this stabilization period. If further correction or enhancement is necessary, you should wait until your eye measurements are consistent for two consecutive visits at least 3 months apart before re-operation.
• It is important to realize that although distance vision may improve after re-operation, it is unlikely that other visual symptoms such as glare or haloes will improve.
• It is also important to note that no laser company has presented enough evidence for the FDA to make conclusions about the safety or effectiveness of enhancement surgery.

Contact your eye doctor immediately, if you develop any new, unusual or worsening symptoms at any point after surgery. Such symptoms could signal a problem that, if not treated early enough, may lead to a loss of vision.

 Cataract Surgery

 What is a Cataract?

A Cataract is a clouding of the natural lens of the eye (behind the iris), usually as a result of normal changes with aging.

What are the symptoms of a Cataract?

The initial symptom is usually glare when light is shining towards the eyes. This symptom progresses, so that vision is blurred even under good lighting conditions. Sometimes near vision becomes the most impaired, sometimes distance and sometimes both. Occasionally double vision occurs in an eye with Cataract.

What is the treatment for Cataract?

The only treatment for Cataract is surgery (usually phacoemulsification) with lens implantation. The patient is given a local pain control medication (anesthesia) and can leave the day of surgery (outpatient surgery).

When is surgery necessary?

Cataract is a normal change that comes with aging and usually is not damaging to the eye. The patient experiences the same results from surgery no matter when the surgery is undertaken. For this reason, the patient can decide if and when he or she wants to have surgery (elective surgery). This decision is based on how the Cataract affects the patient's lifestyle. For most people, the important issues are reading or driving, but the need for surgery may also be based on work or recreational activities.

Rarely, the surgeon will advise his or her patient when to have Cataract Surgery because of a need to see and/or treat retinal pathology or because of inflammation or glaucoma in the eye.

How successful is the surgery?

If the eye is otherwise normal, the chance for a good result with significant improvement in vision approaches 98 percent and the likelihood of serious complications is low.

How is the surgery performed?

Cataract Surgery is usually performed on an outpatient basis under local anesthesia. The procedure takes less than half an hour. There is ordinarily no pain following surgery and the patient can be active as soon as the sedation wears off.

How soon will I see from the operated eye?

Patients have improved vision as soon as the bandage is removed, usually the day after surgery.

Will I need glasses after Cataract Surgery?

Usually the patient has quite good vision without glasses but maximum vision may require some glasses. Individual variations in each patient play a role in how well he or she sees after surgery. Each patient should discuss the choices with his or her surgeon.
