| Risks and Possible Complications All surgery procedures carry an element of risk and are subject to possible complications. These can be minimised by using the best equipment and procedures, as Laservision does, but it is not possible to eliminate all risks completely. It is only natural to want to know what your chances are of obtaining a successful outcome. As with any surgical procedure there can be no guarantees and the outcome depends on the individual's initial refractions. Most people will experience an improvement in their sight immediately after surgery. By the next day, 98% of people see well enough to legally drive. Your sight usually stabilises about two to four weeks after surgery and most of the temporary side effects are resolved in the first three months following surgery. Usually your vision after surgery is as good as it was pre-operatively with glasses or contact lenses. Temporary Side Effects The following side effects are possible but usually disappear over time. In rare situations they may persist.
Below are some of the risks and complications that you should be aware of before making your final decision to proceed with laser refractive surgery. | |  |
| Over-correction / Under-correction Patients sometimes end up under-corrected, over-corrected or with residual astigmatism. In such cases further laser treatment is offered where possible. Flap-related complications In rare cases during LASIK surgery the microkeratome may create an inadequate flap which does not allow laser surgery to proceed. In this situation, the cornea is left to settle and surgery is rescheduled for a later date. Infection Precautions are taken during the surgical procedure to minimise the risk of infection. Antibiotic/steroid eye drops are used post-operatively to prevent infection and reduce inflammation. Glaucoma Steroid drops used over a prolonged period can cause raised intraocular pressure. As the drops are used for a short period of time and you will be monitored carefully post-operatively, this is not a real concern. Inability to wear contact lenses Most patients do not require correction after their surgery. However, of those few patients who do, there may be some that are unable to wear contact lenses. Loss of best corrected vision In very rare circumstances after laser refractive surgery, a patient may have vision that is not as good, even with correction, as it was pre-operatively with glasses or contact lenses. Ectasia There are rare cases where the cornea, after it is thinned by the laser, stretches and goes out of shape. This can result in poor vision that is difficult to correct. At Laservision, care is taken not to over thin the cornea and reject abnormal at-risk corneas, which can lead to Ectasia. It is extremely rare for Laser Refractive Surgery to cause serious visual loss. For more information please see our FAQs page. |
