LASIK, an acronym for Laser-Assisted In Situ Keratomileusis, is a refractive procedure that reshapes the cornea to correct nearsightedness, farsightedness and astigmatism. It is the most common type of refractive surgery. Using targeted laser beam energy, the LASIK procedure reshapes the cornea so that light rays are focused more precisely on the retina, producing clear, sharp vision.
Candidates Eligible for LASIK
LASIK is considered a safe procedure, yet it is not ideal for everyone. A thorough medical evaluation of the patient's eyes must be performed to determine whether the LASIK procedure is appropriate. Good candidates for LASIK are patients who:
- Are over 18 years old
- Not pregnant or nursing
- In general good health
- Have had stable vision for at least 6 months
- Have healthy corneal tissue, thick enough for a flap
- Have refractive errors that fall within the treatable range
It is also important for patients to fully understand the details and risks of the procedure, and to maintain realistic expectations for the outcome.
Benefits of LASIK
One of the primary benefits of LASIK is that patients immediately experience improved vision after surgery. For many people, laser eye surgery can correct their vision sufficiently to permit them to perform all, or most, of their daily activities without eyeglasses or contact lenses. Approximately 90 percent of patients who have undergone LASIK achieve 20/20 to 20/40 vision as a result of the procedure.
LASIK has the advantage of being a short procedure that results in permanent vision improvement. Most patients who choose to undergo LASIK achieve clear vision without corrective lenses while also benefiting from minimal downtime and only mild post-operative discomfort.
The LASIK Procedure
LASIK is performed on an outpatient basis using only numbing eye drops to reduce any potential discomfort. The entire surgery takes less than 5 minutes to perform, although patients can expect to spend a few hours at the doctor's office. If requested, patients can receive an oral sedative prior to surgery to reduce any anxieties about the procedure.
During the LASIK procedure, the patient lies down in a reclining chair as the doctor positions the laser precisely over the eye. A speculum is used to keep the eye open while the eye is cleaned and anesthetic eye drops are administered. A corneal flap is created with either a blade or a laser. The surgeon gently lifts the surface of the cornea aside, enabling the excimer laser to reshape the curvature of the cornea.
The excimer laser delivers customized pulses of light energy based on each patient's prescription. The measurements for customization are determined prior to surgery, with the precise positioning confirmed prior to the start of the procedure. The second eye is treated immediately after the first. Following the surgery, the patient is provided with a protective shield to protect the eyes from bright lights.
Risks of LASIK
Any surgical procedure carries some risks, and patients should be aware that changes to the cornea made during LASIK cannot be reversed. Nonetheless, LASIK is considered safe for most eligible patients. While rare, complications may occur after the procedure, including:
- Undercorrection or overcorrection of vision
- Astigmatism
- Dry eyes
- Flap complications
- Postsurgical infection
- Increased sensitivity to light
- Visual problems, such as halos or night glare
- Fluctuating vision
Only 1 percent of patients undergoing LASIK experience complications.
Recovery After the LASIK Procedure
After LASIK, patients rest in the ophthalmologist's office for a short time before having someone else escort them home. Medication may be prescribed to relieve any discomfort experienced during the first 24 to 48 hours after surgery, but most patients tolerate this procedure well. The doctor will likely recommend a few hours of rest after treatment. Most patients are able to return to work and other regular activities the very next day. Patients who have undergone LASIK are instructed to avoid strenuous activities for at least a week.
Typically, patients experience a significant improvement in their vision immediately after the procedure, but the full benefits of LASIK may not be apparent for several months. While patients can achieve clear vision from LASIK, this procedure does not prevent the development of presbyopia, the age-related vision changes that occur after the age of 40. Many patients will need reading glasses for this condition, but their distance vision will remain clear.
LASIK FAQs
What is LASIK surgery?
LASIK (Laser-Assisted In Situ Keratomileusis) is a popular eye surgery that uses a laser to reshape the cornea, correcting vision issues like nearsightedness, farsightedness, and astigmatism.
Who is a good candidate for LASIK?
Good candidates are typically over 18 years old, have stable vision for at least a year, and have no significant eye health issues. A comprehensive eye exam by an ophthalmologist will determine candidacy.
What should I expect during the procedure?
The procedure usually takes about 8-10 minutes per eye. Numbing drops will be applied to your eyes. After laying down, a laser will reshape your cornea while you look at a target light. Most patients experience mild pressure but little to no pain.
Is LASIK surgery safe?
LASIK is considered safe and effective, with a high success rate. However, like any surgery, it carries risks. Common side effects include dry eyes, glare, and halos, which usually resolve over time.
How long does recovery take?
Many patients notice improved vision within a day or two. However, complete recovery can take a few weeks. You’ll have follow-up appointments to monitor your healing process.
Are there any side effects?
Some common side effects include dry eyes, temporary visual disturbances (like glare or halos), and fluctuating vision. Most side effects resolve within a few months.
How long will the results last?
Most people enjoy long-lasting vision improvement. However, natural age-related changes may affect vision over time, and some may need enhancement procedures later.
How much does LASIK cost?
The cost varies based on location, technology used, and the surgeon’s experience. It typically ranges from $2,000 to $3,000 per eye, and many clinics offer financing options. Call us to discuss options and pricing for you.
Will insurance cover LASIK surgery?
Most insurance plans do not cover LASIK as it’s considered an elective procedure. However, check with your insurance provider for specific coverage options.
Can I have LASIK if I wear contact lenses?
Yes, but you’ll need to stop wearing contacts for 1 week (for soft contact lenses, longer for gas permeable contacts) before your consultation to ensure accurate measurements of your cornea.
What if I have dry eyes?
If you have a history of dry eyes, it’s essential to discuss this with your doctor. LASIK can sometimes worsen dry eye symptoms, but there are treatments available to help manage this.
How do I choose a LASIK surgeon?
Look for a qualified, experienced surgeon with a good track record. Check reviews, ask for referrals, and ensure they use the latest technology. A thorough consultation is also crucial. Dr. Wolsey is fellowship trained in cornea and refractive surgery and has performed thousands of procedures.
What happens if I’m not a candidate for LASIK?
If you’re not a candidate for LASIK, your eye doctor may suggest alternative vision correction options, such as PRK, ICL, or other refractive surgeries.
Can I drive after LASIK?
Most patients can drive within a day or two after surgery, but you will need someone available to drive you home on the day of surgery. Always follow your surgeon’s advice.
