LASIK - Laser Eye Surgery

LASIK or “Laser in situ Keratomileusis” is a form of refractive laser eye surgery used to correct myopia, hyperopia and astigmatism. A thin corneal flap is created using a laser (Femtosecond). Then an excimer laser is used to permanently reshape the central part of the cornea (stroma). This produces a surgical flattening of the cornea. After this the flap is replaced.

What Types Of LASIK Treatment Are There?

LASIK laser eye surgery comes in various forms. Each perform the same laser eye treatment

• Advanced Surface Ablation (ASA)- This type of LASIK reshapes the cornea without the need to create a cornea flap. It is an advanced type of LASIK surgery only undertaken by extremely experienced laser eye surgeons. The recovery time for this type of laser eye treatment tends to be longer than other forms, usually lasting a few weeks.
• Blended Vision– This kind of LASIK treats each eye separately to improve nearsightedness and far sightedness. This procedure balances each eye separately, reshaping one eye for nearsightedness and the other for farsightedness.
• IntraLasik– This form of laser eye surgery is used to create a corneal flap using a laser rather than a blade. Although the time taken to produce the flap is greater than in traditional forms of LASIK, this treatment creates a thinner flap, eradicating imperfections that can be caused by a microkeratome blade. All Optegra LASIK procedures are blade free and use the IntraLasik technique.
• Wavefront (custom LASIK)– This procedure gives the eye surgeon the opportunity to create tailored laser eye procedures that are unique to each patients eye structure. A 3D map of the eye is created by measuring how much light travels through the eye. It is then compared to an eye with perfect vision. This is used as a guide to correct the eye’s vision. This procedure can be used to help improve night vision disorders such as halos and glare. All Optegra LASIK procedures are Wavefront as standard.

Conditions LASIK can correct:

• Myopia- This is the term used for nearsightedness, or short-sightedness. The condition occurs when the eye ball is too long or the cornea is curved too much. During the procedure the front surface of your eye is flattened with the laser.
• Hyperopia - This is the term used for long-sightedness, or farsightedness. It occurs in the opposite way to myopia whereby the eyeball is too short or the cornea is not curved enough. During the procedure the central cornea is made steeper when the laser removes corneal tissue in this area.
• Astigmatism - This term is where the cornea or lens has a slightly different curvature in one direction to the other. It can lead to short or long sightedness and even blurred vision. It is corrected by reshaping the steepest part of the cornea and making it more spherical.

Why LASIK?

LASIK is a popular form of laser eye treatment because it leaves the patient with very little pain afterwards and the results are achieved very quickly. Patients have vision restored by the following day. The procedure is long lasting and offers patients a real alternative to having to wear glasses or contact lenses every day.

How Long Does LASIK Last?

The equipment offered at clinics throughout the UK will vary greatly. Treatment time is dependent on the equipment. Optegra have invested in the most advanced laser in the world - the CONCERTO Excimer Laser. The laser will treat an average patient’s prescription in less than 5 seconds. For example, if you are a -4 prescription, your treatment will last 4.8 seconds. You can be assured that safety and accuracy have not been compromised to gain this advancement in LASIK technology.
