SMILE is an advanced surgery for enhancing vision and is less invasive as compared to LASIK. It is a one-step procedure and provides enhanced and clear vision.
SMILE, also known as Small Incision Lenticule Extraction which is significantly less invasive than LASIK surgery but provides the results like this surgery. Through a focused, computer-guided LASER, the surgeon makes a small incision on the cornea. With the help of this incision, a small corneal tissue is removed which results in reshaping of the cornea. With the help of highly-focused light, the surgery is done with high precision.
The procedure ends within a minute and the patient starts feeling better within 24 hours after surgery.
As compared to PRK and LASIK surgery, the SMILE is less invasive. During the LASIK surgery, a corneal flap of 20 mm is created while in PRK, an incision of 8-mm is created. In the SMILE, the vision is corrected by creating only a 3 mm incision.
Although LASIK surgery is a highly safe procedure complication may arise in a few patients because of the flap creation. SMILE does not cause flap formation and thus, is safer, as compared to LASIK.
Due to the corneal ablations in LASIK surgery through excimer laser, the patient may smell an odor. As SMILE does not use an excimer laser, the procedure is completely free from the odor.
As the SMILE procedure is minimally invasive, the patient may recover fast and the vision is enhanced within a day after surgery. The results of the SMILE procedure are like that of LASIK surgery.
The patients undergoing SMILE procedure have fewer chances of complications as compared to LASIK surgery. There is less risk of halos or glare complications and have less incidence of dry eye syndrome.
SMILE procedure is effective in those patients who do not meet the criteria for LASIK surgery. These candidates include patients with a thin cornea, suffering from dry eye syndrome, and are involved in contact sports.
Both procedures are used to correct the eye vision and to remove the spectacles and contact lenses. However, SMILE is safer as compared to LASIK surgery. The recovery period in the SMILE procedure is also less as compared to LASIK. SMILE surgery is less invasive and there is no creation of a flap in SMILE procedure.
SMILE is developed by using the traditional system of vision correction with the advancement in reducing the side effects. Experienced ophthalmologists should do SMILE surgery.
