LASIK surgery developed into one of the most effective and long-lasting solutions for vision correction treatments. Although it is a fairly simple process, just like any other medical procedure, it does come with its own set of risks and complications. However, these risks can become mitigated significantly if your eye surgeon has years of experience in performing laser eye surgery.
Conditions related to large pupil size
If you have large pupils, you may face visual disturbances such as halos, glare, and other problems related to vision at night. Doctors recommend that patients suffering from this problem wear prescription night vision glasses apart from the residual refractive surgery performed on these patients.
Correlation between pupil size before and after LASIK
People that have large pupil size are not considered as valid candidates for LASIK surgery. They tend to suffer permanent damage to their vision, especially at night. For some patients, the pupil dilates more than the treatment zone which studies show as a common occurrence in people with large pupils. This can further become impacted by the refractive surgery that makes the corneal surface flat. This is the reason the quality of image for these people can decrease, causing the formation of halos from light sources.
LASIK treatment for people with large pupils
A highly advanced LASIK treatment using the Allegretto laser or VISX Star S4 has been considered safe for the people with large pupils. These waverfront lasers come equipped with large pupil software which prevents the worsening or glare or halo formation after surgery. Apart from being suitable for large pupil patients, the laser used in this process is extremely precise which eliminates the risks associated with movement of eye during surgery.
Making the right choice
Despite the technological advancement in the field of LASIK surgery, patients exist with large pupils that are not medically suitable to undergo the vision correction procedure. During the surgery, the size of the treatment zone needs to be increased to accommodate large pupils; they not only need the larger area, but need thicker corneas that can leave at least 250 mircons untouched during the procedure.
As a patient, you need to check with your eye specialist during pre-operative examination if you are suitable to undergo the LASIK treatment or not. A reputed medical institute like Sugarland Eye & Laser Center in Houston will conduct a comprehensive examination of the eyesight to calculate the size of the treatment zone as well as the corneal thickness before recommending the surgery to you.
Although LASIK is an effective method to fix the visual acuity with faster recovery, it is a medical process that needs you to have complete compatibility with the surgical mechanisms to enjoy its full health benefits.
