Understanding SMILE.

The latest advancement in the laser vision correction or near-sightedness and astigmatism, SMall Incision Lenticule Extraction (SMILE) offers the same accurate outcomes and rapid recovery as LASIK, but with additional advantages.

SMILE

A femtosecond laser creates a disc (lenticule) of corneal tissue inside the cornea as well as a small incision. The surgeon removes the lenticule through the tiny opening, which allows for the cornea to be reshaped. The major advantage of SMILE over LASIK is the lack of a flap. The least invasive refractive procedure in the world, SMILE leaves the surface of the cornea almost completely untouched, allowing SMILE patients to benefit from less dry eye and more stable results over time.

SMILE pro

Lumea offers the option of ZEISS VISUMAX 800 for SMILE pro procedures. This technology allows for the creation of the lenticule in under 10 seconds, which reduces the total laser time compared to previous standards. The shortened duration is designed to decrease the time the eye is under suction and pressure, while the ergonomic, open design is intended to assist with patient positioning.

Robotic Assistance and Alignment

The VISUMAX® 800 incorporates robotic assistance features, specifically CentraLign® and OcuLign® technology. These systems are designed to automatically compensate for eye rotation during the procedure. This technology maintains centration and alignment without the need for manual adjustments, which is particularly relevant when treating patients with astigmatism.

Possible Side Effects and Complications

Possible side effects of SMILE are mild and include temporary dry eyes and foreign body sensation. Patients may experience night glare or halos for a few days, which quickly resolves with normal healing. Complications of SMILE are extremely rare and are treatable. These may include infection, swelling, or inflammation.
