LASEK (laser-assisted epithelial keratomileusis), is a refractive surgery specially designed for patients with thin corneas. LASEK can improve vision for those who suffer with nearsightedness, farsightedness, and astigmatism.
Many eye care patients think that they are not candidates for LASEK because they have high prescriptions. In the past, this was a real problem—laser eye surgery in its early years was not well equipped to help those with severely restricted vision. However, as technology has improved, this limitation has been overcome. With modern procedures, surgeons are able to correct prescriptions as high as -12.00. This makes almost everyone a candidate for LASEK, even those with extremely high prescriptions.
In fact, patients with severe vision problems are often the best candidates for LASEK. For some conditions, particularly astigmatism, LASEK can actually correct the problem better than any contacts or glasses. Patients with severe astigmatism will usually have better vision after LASEK than they did with corrective lenses before their procedures.
If you have a high prescription, you may still be a candidate for LASEK. Even if you’ve been told before that your prescription was too high, come in for a consultation. With the latest technology, you are probably a great candidate.
The maximum treatment varies, based on several important factors, most prominently the thickness of the cornea. Different doctors have different criteria that they use when determining maximum treatment. For some doctors, 8 diopters is the maximum, while others feel comfortable treating up to 12 or 14 diopters.
