Laser Sight Correction Treatment
Assessment for LASIK, LASEK, and Other Refractive Surgery Procedures at Our London Eye Practice
Whether you are short-sighted, long-sighted, astigmatic or just need reading glasses (presbyopic), we can advise.
The original optical properties of the cornea need to be taken into account in advising on a corrective treatment, otherwise visual quality may be degraded causing side-effects like glare and poor night vision. Some treatments change the shape of the cornea in an arbitrary way that is unsympathetic to the original optics, the way our eyes work. Mr Bailey will advise you, taking into account your expectations, your life style, your occupation and the main purpose that you want eye correction for.
We use maps of the eyes optics (wave-front) or maps of the shape of the surface of the eye (topographic) at our London eye practice to take into consideration any distortion of the surface of the eye, for example by injury or other surgery.

Assessment for Laser Eye Treatment
Proper assessment is absolutely essential prior to treatment. Not all Lasik treatment centres have time to go through the Individual's vision requirements in relation to their life style and expectations. Mr Bailey has been doing laser surgery since 1990 and is an examiner in Laser Refractive Surgery for the Royal College of Ophthalmology. Medical Care - we offer a wide range of ophthalmic medical services.
LASIK (Laser assisted in-situ keratomileusis)
LASIK is the mainstay of modern laser refractive surgery. When performing LASIK a thin flap of corneal tissue is made with a special laser called a 'femtosecond' laser or occasionally with a surgical instrument called a microkeratome. The underlying corneal tissue is then reshaped with a laser beam and the corneal flap is replaced. The surface skin of the eye is not disturbed in LASIK eye surgery because it is attached to the flap.
'All-laser LASIK', where the flap is made with a femtosecond laser, is preferred for many treatments for reasons of safety and accuracy. However, some treatments call for the use of a microkeratome.
The advantages of LASIK eye surgery are that minimal, if any, discomfort follows the procedure. The visual recovery is very fast, with most people meeting the driving standard in about twenty-four hours. Final visual stability is usually reached within a few days, although there may be a very small change over a couple of months or so. Up to approximately 12 dioptres of myopia with or without astigmatism and about four dioptres of hyperopia with or without astigmatism may be treatable, depending on the individual.
PRK (Photorefractive keratectomy) and LASEK (laser assisted sub-epithelial keratomileusis)
For patients who are unsuitable for LASIK surgery, PRK, LASEK and epi-LASIK are all surface treatments that differ from one another only in detail. All involve sculpting the corneal material that is directly beneath the surface skin of the eye.
Surface refractive surgery procedures can be used with confidence for correcting myopia up to four dioptres, astigmatism up to three dioptres, and hyperopia up to two dioptres. It is possible to treat more dioptres, but generally less reliably than with LASIK. Visual recovery is slower than with LASIK so it is usually sensible to treat one eye at a time.
Latest advances allow tissue to removed from within the cornea with barely any disturbance to the surface at all. This can have advantages in retaining corneal strength and allowing higher amounts of correction.
