Laser Eye Technology

Talya Medical Center uses the latest technologies and devices all for your comfort and best results. Since there are a lot of different treatments we would like to inform you :

LASIK/Intra-LASIK (Laser Assisted In Situ Keratomileusis) is the most advanced refractive surgery procedure currently available.

It is also a very successful technique: quick, painless, and most patients are completely delighted with the results. The treatment is carried out as an out patient procedure and both eyes are usually treated at the same time. You will be able to play sport and socialise without glasses a short time after the treatment – full visual recovery is usually just 2 – 7 days.

Originally a precision surgical device was used to create a small 'flap' in the surface of the cornea, and excimer laser treatment was then applied underneath. Now however the routine method used at Talya Medical Center to create the corneal flap involves another laser – the femtosecond laser – which is more accurate and therefore safer. The technique is termed intra-LASIK. Talya Medical Center has recently installed the latest version of this laser – Visumax Femtosecond Laser device. The computer-guided excimer laser beam is then focused on the corneal surface and permanently reshapes the cornea by precise selective tissue removal. When the laser treatment is finished, the flap is repositioned, where it settles back into place, and the procedure is complete. LASIK takes around ten minutes for each eye.

LASEK and PRK are similar procedures to LASIK, but the laser treatment is carried out on the surface of the eye after removing a thin layer of epithelium (a protective layer of skin at the front of the eye) from the cornea. These options are generally used for patients who have normal but relatively thin corneas or who lead an active lifestyle which includes contact sports, and therefore might be unsuitable for LASIK.

These treatments are just as simple to perform. The recovery period is longer than that of LASIK, because the surface tissues need time to heal, and patients are asked to take 1 week off work (as compared with 48 hours for intra-LASIK), but final visual results are just as good as LASIK or intra-LASIK.

Surface laser procedures take about 10 minutes for each eye. Anesthetic drops are applied to the eye to make the operation painless. The eyes are typically sore and light sensitive for 3-4 days after surgery, and drops and special contact lenses are used to minimise discomfort during this period.

Wavefront scanning is a new technology which reveals how your entire optical system processes light.

A Wavefront scan produces a map of the actual focusing requirement at each point on your eye, which is different for every individual. It can be compared to having a fingerprint taken for each eye.

Wavefront LASIK and surface treatments build information from a Wavefront scan into the pre-programmed pattern of laser treatment used to correct your sight. The procedure is otherwise identical to conventional excimer laser treatment, and is used to correct the same range of refractive errors.

The advantages of Wavefront over conventional laser treatments are thought to include greater accuracy and improvements in visual quality. Wavefront treatments also include additional elements such as iris registration, or even iris recognition, and pupil size measurement in order to be more precise. The latest excimer lasers in use at Talya Medical Center for example can offer ‘dynamic rotational tracking’ of eye movements in order to achieve greater accuracy. It should be emphasised, however, that conventional laser refractive surgery already produces very good results and that Wavefront treatments do not routinely produce supervision, or vision that is better than the normal level for a non-spectacle wearer.
