PRK (photorefractive keratectomy) uses the same excimer laser as the LASIK procedure to reshape the outer layer of the cornea to correct for nearsightedness, farsightedness, and astigmatism. However, unlike LASIK, no flap is created in the cornea and the laser is applied directly to the surface of the cornea. This treatment is especially useful in some patients not suitable for LASIK due to the shape or thickness of their cornea.
Reasons to consider PRK:
Astigmatism (irregularly shaped cornea).
Cornea too thin for LASIK.
Pupil too large for LASIK.
In preparation for surgery, anesthetic eye drops are administered. Next, a speculum is placed in the eye to keep the eyelids open, which is normally not uncomfortable. While the patient fixes his or her gaze on a target, the laser reshapes the cornea by removing tissue (a process called ablation), which is controlled and closely monitored by the doctor. The laser is actually guided by a detailed map of the patient’s eye which has been programmed into a computer beforehand. The ablation usually takes around a minute for each eye, depending on how high the patient’s vision prescription is. Most patients feel no pain during the procedure. After the procedure is complete, a bandage contact lens is placed on the eye. The patient may go home shortly after the procedure; however, someone else must drive or alternate transportation must be arranged.
The doctor may prescribe pain medication for recovery; however, most patients don’t require it since only minor discomfort is experienced. The doctor will also schedule several check-up appointments to monitor the healing process, followed by periodic visits over the next several months. During the recovery process, the patient should rest, and refrain from any strenuous activities for at least a week. Most patients can return to work in a day or two, though it is best to take a few days off to ensure a smooth recovery.
What sets us apart from the high street?
1) Surgeon-delivered care
In the UK, most laser eye surgery is delivered via a few large high street chains. As a result, you usually see an optician at your pre operative consultation rather than the surgeon who will treat you, and your follow up appointments are often with different opticians. In contrast, you will have a detailed assessment at your first consultation with the surgeon that will treat you, and any post-treatment consultations will also be with your surgeon.
2) Highly trained
James is a highly trained corneal transplant surgeon, indeed being responsible for managing corneal disease and transplantation in the NHS for over 1 million patients in South Essex. He has a research interest in the surgical management of corneal conditions and has extensively published research on the subject. He trains other surgeons around Europe in the latest surgical techniques via the European Society of Cataract and Refractive Surgery (ESCRS). As a result, he is only interested in choosing the safest and most effective treatment for your eye, based on an in-depth assessment of each individuals corneal biomechanics and visual requirements.
Although initial consultations on the high street may be local, the treatment itself is often performed in another city, where the laser and surgeon are based. We are the only hospital locally that has both the equipment and expertise to perform both consultations and treatment under one roof.
