Safety Information and Refractive solutions for Thin Corneas
In the “Journal of Refractive Surgery” from the December 2017 issue Dr. Montserrat Garcia-Gonzalez Et al. talk about corrective options for thin corneas and benefits to using mitomycin C (MMC) in the article titled “Long-term Follow-up of LASEK With Mitomycin C performed to Correct Myopia in Thin Corneas”.
Some studies have shown that when performing LASIK on thin corneas with a reading of less than 500 microns, it can decrease the overall strength of the cornea which is the transparent layer forming the front of the eye. A weak corneal structure can lead to ectasia which can be described as a condition where the cornea will start to bulge forward. By using alternative procedures such as advanced surface ablation (ASA or PRK) it can reduce corneal weakening because it leaves a thicker residual stromal bed which makes up a large part of the cornea. With surface ablation used to correct Myopia, a medication called mitomycin c (MMC) is helpful in aiding healing postoperatively. The medication reduces the risk of forming corneal haze after surface ablation which helps to maximize long-term visual results.
In conclusion as noted in the article “Long-term Follow-up of LASEK With Mitomycin C performed to Correct Myopia in Thin Corneas”, surface ablation with the intraoperative use of MMC seems to be a safe and effective way to treat corneas with a thin micron measurement. In addition to safety the long-term effects provide good visual and refractive outcomes with no topographic signs of corneal ectasia in a mean 6.5-year follow up.
