Advanced Surface Ablation or ASA is a method of laser vision correction without the need to cut a flap. ASA includes procedures such as LASEK. Our procedure involves softening the outer surface of the eye (epithelium) with very diluted alcohol which is then carefully removed. The excimer laser is then used to treat the surface of the cornea directly and the amount of treatment is dependent on the individual’s prescription. At the end of the procedure, a soft ‘bandage’ contact lens is applied to aid healing and improve comfort. The bandage lens may remain in place for up to a week depending on how quickly healing occurs. Visual recovery is slightly slower than with LASIK and there may be pain or discomfort while the eye is healing (3-4 days). The vast majority of patients achieve equivalent results to LASIK in the long term. The advantage of ASA is that the cornea is more stable following surgery and it is more suitable for some patients. Example: those with thin corneas or those with active/vigorous lifestyles like military personnel, policemen or those involved in contact sports.
