The department provides a range of laser correction services, including laser in-situ keratomileusis (LASIK), surface ablations, refractive lenticule extraction (ReLEx), small incision lenticule extraction (SMILE), phakic intraocular lens surgery and refractive cataract surgery.

LASIK is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. The technology has advanced from using a blade to bladeless surgeries. Meanwhile, LASIK Xtra- is an enhanced LASIK procedure with an add-on corneal strengthening procedure (cross-linking).


LASEK (Laser-assisted subepithelial keratomileusis) is an example of an advanced surface ablation procedure. It is a method of laser vision correction that does not require a flap to be cut, and is suitable for individuals with thin corneas and those with active and vigorous lifestyles.
ReLEx • SMILE is a technique of laser vision correction that does not create a flap and involves the use of a femtosecond laser only. This technique results in less severe immediate post-operative discomfort and tearing and no risk of flap dislodgement.

Intraocular lenses (ICL) including the implantable collamer lens, are artificial lenses that are implanted into the eye to correct refractive errors. The procedure is performed without removing the eye's natural lens and is usually suited to patients with very high refractive errors or thin corneas.
