The Risks and Disasters Involved with Laser Eye Treatment

By Edited Nov 13, 2013 0 0

Strict screening procedures are currently in place to determine who the patients eligible for laser eye treatment are. These pre-operative guidelines will help decrease the risks and disasters involved with laser eye treatment. Because of this, not all patients are qualified to undergo this type of eye surgery and this rate is comparatively high as those who are entitled to this procedure. However, rejected patients are the ones who will benefit from the current studies being conducted in this rising field of medical engineering.

Today’s lasik and PRK procedures are so innovative that the risk of getting blind is nearly negligible. In its first few years, however, some procedures ended up with the flap not adhering securely to the eye at the hinged segment. Because of this, deep cuts in the eye resulted which gave considerable pain to the patient and would sometimes bring about blindness. Thanks to intralase technology, the process of creating a flap has become more accurate because of the accuracy and precision of using laser. This issue has now been resolved and has seldom become a problem during laser eye surgeries.

In recent years, the most pressing topic involved with laser eye treatment is primarily concerned with the quality of visual acuity post-operation. For example, patients were either under-corrected or over-corrected. This means that residual prescriptions are present and the patient would need to resort to eyeglasses or contact lenses to have clearer vision. When this happens, a subsequent surgery is an option to improve vision. Ophthalmologists recommend only two procedures within the first six months of the laser eye treatment though.

Post-operative complications are also normal occurrences. These symptoms include dry eyes, night time glares and haloes. Dry eyes result from the eye’s real tears not clinging to the cornea because of the irregularity of the front surface of the eye as a result of the surgery. This can be treated with lubricants which will make recovery faster, decreasing the dry eye syndrome in the course of the following months. For some patients, dry eyes tend to become a lifelong suffering which means that they would need lubricants indefinitely. An extensive corneal examination should prevent this from happening since the goal of this procedure is to rule out any pre-existing surface conditions that could exacerbate dry eyes after the surgery.

Night time glares and haloes, on the other hand, are caused by pupil dilation that exceeds the area of the eye as the edge of the flap causes visual interference. These symptoms are not as complicated as dry eyes and usually disappear within the next few months. Intralase technology was created to also resolve this problem through the creation of a more precise flap. Patients still report satisfaction with laser eye treatment despite the presence of glare even without intralase.

For any treatment involving the eyes such as laser eye treatment, the risks and complications should always be weighed. The outcome should outweigh the risks involved with improving visual acuity and if you are unsure, local optometrists and ophthalmologists should be consulted to provide sound advice when it comes to eye surgeries.
