An artificial lens can be implanted into the eye in front of the patient’s natural crystalline lens through a small incision in the cornea. The advantage of ICL is that it is able to correct very high degrees of myopia and hyperopia, in addition to astigmatism.
Unlike LASIK or Advanced Surface Ablation which are external ocular procedures, ICL is a more invasive intraocular surgery. Its potential risks, albeit small, are more serious. This includes corneal swelling, intraocular inflammation, glaucoma, cataract, retinal tear and intraocular infection.
As such, ICL is only recommended as a secondary option for patients who are not suitable for LASIK or Advanced Surface Ablation but are still keen for refractive surgery.
Corneal inlays are implants inserted within the substance of the cornea to enhance near vision. It reduces the need for reading glasses in patients who has presbyopia (old-sightedness).
A small, thin circular disc, with a pinhole in the centre is placed in the cornea under a corneal flap created with the Femtosecond Laser. This procedure is performed in one eye only and can be combined with LASIK to correct other concurrent refractive errors.
The pinhole effect of the inlay allows the patient to see near and far objects over an extended range of distance.
Corneal cross-linking is a procedure whereby Riboflavin (Vitamin B2) eye drops and Ultraviolet (UV) light are used to strengthen the cornea by inducing cross bonding of the collagen fibres within the cornea, thereby preventing corneal warpage over time. It has been used by some centres in combination with LASIK to strengthen the cornea after Excimer Laser ablation. However, its main application is in treating conditions such as keratoconus and post-LASIK corneal weakening.
