DescriptionLASIK (Laser-Assisted in situ Keratomileusis) is a laser eye surgery to reshape the cornea to correct vision problems (myopia person has blurred far vision, hyperopia person has blurred near vision, astigmatism blurred vision due to irregular shape of cornea or lens). It is commonly known as laser eye surgery.There are two types of LASIK available:1. In Traditional LASIK or Blade LASIK, Microkeratome is used to cut the cornea to create a flap. It is also called as blade flap.2. In Bladeless LASIK, femtosecond laser is used to create the corneal flap. Traditional LASIK Blade LASIK Bladeless LASIK
SymptomsThe LASIK surgeon will assess if the patient fits into the criteria for LASIK surgery.A patient is a candidate if The patient is 18 years or elderVision is stable for at least a yearCorneal thickness must be adequateHealthy eyes No other eye diseasePregnant or Lactating mothers should wait till the female sex hormones are normalAny other disease Autoimmune diseases, Infections, etc. The patient is 18 years or elder Vision is stable for at least a year Corneal thickness must be adequate Healthy eyes No other eye disease Pregnant or Lactating mothers should wait till the female sex hormones are normal Any other disease Autoimmune diseases, Infections, etc.
Pre ProcedureBefore the LASIK surgery:-1. The doctor first takes your detailed history & then examines your eyes to make sure there is no other eye disease & checks if they are healthy for the procedure.2. After your doctor confirms that you are a fit candidate for the procedure, he/she will evaluate parameters of different parts of your eyes thickness of cornea, pupil size, status of your refraction (vision), pressure of your eye, etc.3. A corneal topographer is used to measure the curvature of cornea & creates map of the same. Some new technologies are also being used to measure the same.4. Your doctor will instruct you not to wear contact lens for about 2 weeks before the procedure.
During ProcedureAn eye surgeon (ophthalmologist) who is trained in LASIK surgery performs the surgery.The ophthalmologist takes approximately 10 20 min to perform the procedure.Both eyes can be done at the same time.During Procedure:-1. The doctor will instill anesthetic eye drops into your eyes to make the procedure pain free. However, some patients may feel some discomfort during the procedure.2. After positioning the eyes under the laser, lid speculum is used to keep your eyes open. A suction ring is used to prevent eye movements.3. After marking the cornea, the surgeon creates a thin, circular flap in the cornea with the help of surgical instruments (microkeratome or femtosecond laser).4. After folding back the thin flap, the corneal tissue is removed with the help of excimer laser.5. The reshaping of cornea is done according to the need of the patient. For farsightedness, cornea is steepened; and for nearsightedness, cornea is flattened. For astigmatism, corneal surface is smoothened.6. After reshaping the cornea flap is put back in place & is allowed to heal naturally. No stitches are needed for the incision on the cornea.7. After one eye, the surgeon operates on the other eye.
Post ProcedureDuring LASIK surgery, a permanent reshaping of cornea is performed. However, with time, some changes in your eyes, such as age related changes, glaucoma, cataract, macular degeneration, etc, may affect your vision.The patients return to normal activity the next day, however, rest is advised for few days.The cost of LASIK may varies from 30,000 INR to 1,25,000 INR depending upon the type of technology used & the type of healthcare institution.
Risk And ComplicationsComplications/Risks of LASIK:- Like any other surgery, there are risks associated with LASIK surgery. Very rarely, the patients experience side effects of LASIK. Infection of eye after the surgeryUnder correction or over correctionYou may experience glare, halos, dryness in eyes, hazy vision.The corneal flap created during the surgery may fail to adhere back to the cornea. It may lead to formation wrinkles in the cornea, causing blurred vision.Deformity of the cornea Infection of eye after the surgery Under correction or over correction You may experience glare, halos, dryness in eyes, hazy vision.
