1. What is LASIK
LASIK is a refractive procedure done to correct nearsightedness (myopia), far-sightedness (hyperopia) and astigmatism. LASIK modulates the shape of the anterior surface of eye (Cornea) so that the power of glasses is almost eliminated.
2. What procedure is done in LASIK
During LASIK, a thin corneal flap is raised (less than 150 microns) and the shape of cornea is modulated with laser beam after which the corneal flap is replaced. The total procedure time on each eye is 2-5 minutes. During the procedure the patients lies down on an automated resting couch which aligns the patient with the LASIK machine. Topical anesthetic drops are applied and the patient is asked to look straight, not to move the eyes and be completely relaxed. The surgeon always help the patient by communicating to him/her.
3. How long has LASIK been performed
LASIK was 1st introduced in the year 1989 and since then it has been performed in millions of eyes successfully. It is the 2nd most common surgical procedure performed in the eye around the world. It is also the most commonly performed cosmetic procedure in the eye.
4. What is Customized LASIK treatment
In a Customized LASIK treatment, the LASIK not only treats the power of glasses, but also reduces the higher-order aberrations (which can never be corrected by glasses/contact lenses). After this treatment, the patient may achieve Supra-Normal Vision (that is better than normal 6/ 6 vision).
5. Am I an eligible candidate for LASIK
The ideal candidates include those who:
- Are age over 18 years
- Have a stable refraction (glasses or contact lens power) for at least an year
- Have sufficiently thick cornea (based on scan reports)
- Do not suffer from any diseases of the eye or the body
- Understands the nature of surgery and expected results
- Are able to comply with the post LASIK instructions religiously
- Are willing for treatment and give their informed consent for the procedure
6. What tests are done to evaluate eyes for LASIK
A complete examination of the eye including vision, refraction, Slit Lamp and Fundus examination, eye pressure measurement is done. This is followed by LASIK-specific tests namely Orbscan, Aberrometry, AS-OCT, etc. More than one test is required for the complete evaluation of a patient.
7. If I am not eligible for LASIK, what are alternative treatment options
If the doctor decides that you are not eligible for LASIK, he may perform some more tests and will advice you one of other refractive procedures namely PRK, Epi-LASIK, Phakic IOL, etc. Details of each of these tests are explained to the patient during counseling.
8. How much does LASIK cost
The cost of the procedure will depend upon the technique of flap-making, the results of the tests and the type of LASIK laser setting required. The total cost is explained during the counseling.
9. What results can I expect from LASIK
Same day of the treatment, the patient is able to achieve his best-spectacle corrected vision without using the spectacles. Clarity of vision gradually improves over the next few days to its maximal level. Some patients may experience some difficulty while reading on the 1st post- operative day which soon recovers.
10. Will I need to wear glasses after LASIK
NO. LASIK treatment has been done to reduce your dependence on glasses. You will not be requiring glasses for your routine work.
11. Are the results of LASIK permanent
YES. Absolutely YES. LASIK laser treatment permanently modulates the corneal shape.
12. If I have LASIK and my vision changes later in life, can LASIK be redone
LASIK is a once-in-a-lifetime procedure in almost all patients. Very few patients may require enhancement LASIK if the needs arises so within the limits of the procedure.
13. Does the LASIK procedure hurt
NO. There is no pain during or after the procedure. The patient may feel some pressure over the eye which lasts for a few seconds.
14. What kind of anesthesia is used in LASIK
Topical anesthetic drops are applied. No injections are given to the eye.
15. How safe is LASIK procedure
LASIK is one of the safest procedures performed over the eye all over the world. The safest profile of LASIK procedure is very high. The LASIK machine is mostly automated and operated by highly skilled refractive surgeons thus increasing the success rates.
16. Can I have both eyes done with LASIK at the same time
YES. We perform LASIK on both eyes one by one in the same sitting.
17. Do I have to get admitted in the hospital
No. LASIK is a day-care procedure. You will have to arrive in the morning on the surgery appointment day and can go back by afternoon. The day of surgery you should take rest at home.
18. Do I have to take complete bed rest and restrict my daily routine
NO. There is no need of bed rest or restricting your daily routine. Few precautions are essential to be taken care of. These are general precautions given to all patients undergoing surgical procedures in the eye.
19. Can I drive immediately after LASIK
NO. As the clarity of vision takes a few days to improve, a few patients may experience halos and glare in the initial few days. Thus driving should be restricted at least for a week. Protective glasses should be worn all time during driving for at least a month.
20. Can I do swimming, jogging and gym exercise soon after LASIK
NO. All these exercises are not to be performed for at least a month after LASIK. The LASIK flap is very thin and any strenuous exercise can disturb the flap.
21. Will the appearance of my eyes change after LASIK
NO. LASIK does not change the appearance of the eyes.
22. Can I get LASIK done if I am pregnant or lactating
NO. LASIK should be avoided during pregnancy and lactation.
23. How long will it for me to work comfortably on computer after LASIK
Initially you should use computers for shorter durations. Slowly, the durations of use can be increased with frequent breaks in between to give rest to the eye. Religious application of lubricating drops is very essential.
24. Why do I have to use medications for few months after LASIK
The healing process generally completes within 1 month. As the body response varies from individual to individual and may take longer time, we advice all our patients to medications for 6 months.
25. How much time it takes for pre-LASIK investigations
Depending upon the cooperation levels of the patient and effects of topical drops, it may take from 3-5 hours for complete workup of a LASIK patient. During this period, we suggest the patients to be comfortable and not to be anxious. A calm patient will be able to cooperative better and thus shortening the total time.
26. How frequently I have to come for follow-up
Initially, for the 1st month you will be called upon 3-4 times. Following this, you will be called after 3-6 months and thereafter yearly once. As the body’s healing process varies from person to person, follow-up visits may vary.
27. If I have more questions about LASIK whom should I contact
You are always welcomed to clear all your doubts with the refractive surgeon and the counselor. You can also contact us on the below mentioned numbers for further information.
