Lasik Surgery

SMILE is an acronym for Small Incision Lenticule Extraction and is today’s state-of-the-art refractive laser surgery. It also corrects myopia and astigmatism. The surgeon uses a femtosecond laser to create a small bit of tissue (lenticule) within the cornea. Then, with the same laser, an incision is made in the surface of the cornea, and the lenticule is extracted and discarded. The removal of the lenticule alters the shape of the cornea and thus corrects nearsightedness. The corneal incision quickly heals without stitches, and sharper vision occurs very quickly. SMILE presents some benefits in comparison to the other surgeries – A comparative table with the different surgery types is available below – check it out!

Intra-Lasik (Femto)

Lasik Surgery

Intra-Lasik surgery is the gold standard for refractive surgery and is the third generation of refractive laser surgery. It is a blade-less surgery that creates the eye flap through use of a femto second laser. Once the flap is made and lifted, the cornea is then reshaped. Intra-Lasik provides multiple advantages over PRK and Lasik – A comparative table with the different surgery types is available below – check it out!


Lasik Surgery

Lasik Surgery is a variation of the PRK surgery and is considered the second generation of refractive laser surgery. It also corrects myopia, hyperopia and astigmatism. The main difference between Lasik and PRK is that a flap is created on the cornea with a microkeratome, and lifted to access the internal cornea tissue. The cornea is then reshaped with an excimer laser.


Lasik Surgery

Photorefractive Keratectomy (PRK) is a laser surgery to correct myopia, hyperopia and astigmatism. PRK was the first type of refractive laser surgery and is still a popular option. The thin layer of the cornea (epithelium) is removed (don’t worry it grows back!) and then the cornea is reshaped with an excimer laser. The recovery time for PRK is longer than LASIK but is still quite common as it provides advantages over LASIK for some patients – trust your doctors’ advice!

Other procedures performed at the BESH Refractive Surgery Center


Cross-Linking (CXL) is a procedure (in-clinic) that is performed to strengthen the cornea.

Multiple conditions can lead to the weakening of the cornea.


Presbyopia is the condition when an individual has to wear glasses to read (age related).

BESH is the only hospital in Lebanon that provides laser treatment to eliminate Presbyopia.
