Laser Eyesight Correction
Some of our patients have benefited from new laser technology and have undergone laser refractive surgery. At Harris, Blake & Parsons we are an accredited referral practice for Laser Sight Centres and our optometrists can provide you with professional advice and information about laser eyesight correction.

explain the benefits and risks of laser treatment
assess your suitability and the best treatment method
arrange referral to an appropriate surgeon
carry out pre-operative examinations at our practice
most post operative care can also be done locally at our practice
How does it work?
The excimer laser used in laser vision correction causes the cells of the cornea to be "excited". They then break apart and essentially vaporise. In this way the cornea is reshaped to allow for your spectacle or contact lens prescription.
Latest equipment used by our expert eye doctors.
What are the types of laser vision correction ?
The two main types of laser vision correction are LASIK and PRK. Both use the same laser, however the way the eye is prepared for the laser differs. In LASIK a flap of corneal tissue is folded away before the laser beam is applied. In PRK only the surface layer of the cornea is removed before the laser beam is applied.
A new modified technique, LASEK has recently been developed where the surface layer (epithelium) of the cornea is gently separated and pushed aside prior to the laser beam being applied, it is then placed back into position.
Visual recovery is usually slower for PRK and the eye is uncomfortable for several days, however it causes less thinning of the cornea and is sometimes preferable to LASIK.
What is wavefront technology?
Wavefront technology was first developed in Germany in the late 1970's and today is widely regarded as a major advance in laser vision correction. Thanks to this new wavefront technology, laser vision correction can not only treat your refractive error (long or short sightedness), it can also correct subtle imperfections and scattered light errors (abberations) that are exclusive to your eyes, resulting in a remarkable vision quality.
