How is the number removed in Lasik?
The cornea of the eye is made up of 5 layers. In Lasik, a very thin flap of the 1st & 2nd layer of the cornea is made by a special instrument called a microkeratome. The flap is hinged at one end of the cornea. Excimer laser is than applied to the 3rd layer of the cornea to reshape it & then the flap is replaced back. This procedure does not require any incision on the cornea nor does it require any stitches. The flap sticks by itself.
Who can undergo this treatment?
Anyone who were spectacles or contact lens can undergo this treatment but this treatment is usually recommended after 18 years of age when the eyeball stops growing. Even after this age refractive error should be stable over a period of 1 year before this treatment is contemplated.
Situations where this is not recommended:
A) Age below 18 year. B) Unstable number or constantly changing number in childhood. C) When a patient has only one eye with good vision. D) Pregnancy E) Severely dry eyes. F) high hypermetopias i.e. + numbers G) Reading numbers.H) Patients wearing bifocals. I) Very high cylindrical numbers. J) Corneal opacities & other corneal pathologies.
How long is the treatment ? Is it painful ? Is it safe?
The entire process takes about 10-15 minute of which the laser treatment itself takes a minute or two. The treatment is not painful as the cornea is made numb with eyedrops. No injections are given. Only there might be a slight discomfort during & after the procedure. The treatment is extremely safe & also the patient can go home after the treatment within half an hour.
Is there a chance of the refractive errors coming back in the long run?
What are the advantages of Lasik compared to other refractive procedures?
Very little pain & discomfort post-operatively in Lasik b) Post-operative vision is restored within hours to a few days in Lasik c) Greater predictability of correction.d) less follow up visits e) Preservation of all corneal layers.
Can both eye treatment be done on the same day?
What are the results of refractive surgeries?
The reliablility of Lasik os very good in mild to moderate levels of refractive errors but with very high degrees of refractive errors (number above – 10), the variability is more & some people may still need glasses though of much lesser power.The results are excellent in myopia(minus numbers) as compared to hypermetropia (plus numbers) Lasik technique can correct: A)Myopia from -1to 18D B) Hypermetropia from+ 1 to +6D C) Astigmatism Cylindrical numbers from 1 to 6D.
What is the care to be taken after Lasik treatment ?
Usually the patient can get back to work in 2-3 days after the treatment without any problem. However the following care should be taken after Lasik:
Thus Lasik treatment is a boon as well as a dream come true for :
