What is commonly known as LASEK eye surgery actually refers to a number of very similar forms of laser eye surgery: PRK, LASEK, ASA, Epi-LASIK and Epi-LASEK.
These procedures are all minor variations on the same surgical theme. They are what is known as surface procedures – varieties of the original form of laser eye surgery, known as excimer laser photorefractive keratectomy (PRK).
PRK eye surgery was introduced in the 1980s, and has successfully transformed the vision of millions of people. Since the early 1990s, it has evolved into what is now known as advanced PRK, or Advanced Surface Ablation (ASA).
In all surface procedures, instead of creating a flap, the surgeon removes the cornea’s outer skin (epithelium), and uses the same laser to reshape the exposed substance of the cornea. The surface skin then grows back over the next few days.

Scientific comparison of these varieties of PRK has shown no differences between them in terms of results. However, studies have shown that advanced PRK offers slightly faster recovery, and slightly less discomfort than the others.
At the London Vision Clinic, we now only use PRK for 5 to 10% of patients. These tend to be those with unusually thin or flat corneas for whom LASIK eye surgery would be impractical.
However, because the cornea’s surface is mechanically removed in PRK, the levels of discomfort and recovery times are both higher than with LASIK. Generally, your vision will be good enough to drive a car within two to three weeks following your LASEK eye surgery, but you may not achieve your best vision until between six weeks and three months after surgery.

The surgeon, Mr Carp, was outstanding. From the moment I entered his surgery, and receiving a phone call from him in the evening at home, he was reassuring, compassionate and utterly professional.

Ms Morral provided a very professional yet comforting and attentive service as a surgeon, thoroughly engaging me in all aspects of pre and post op concerns I had.
