Iris chafing syndrome after scleral-fixated intraocular lens implantation.

Manual capsulorhexis creation is especially challenging in cases inwhich an intumescent cataract coexists with an adherent leukoma. Under the operating microscope, even macular-grade scars are hard to visualize through because of light scatter and this makes it difficult to determine the status of the anterior capsule. Intraoperative AS-OCT was advantageous in our case as it was able to image through the scar and the advanced cataract. Although the laser treatment through a scar is poor, the ability to customize the laser to treat through central and paracentral clear cornea permitted a successful, albeit smaller, capsulotomy, enabling successful completion of the surgery. Femtosecond laser–assisted cataract surgery is contraindicated in cases with severe corneal opacities and corneal abnormalities. However, in eyes with a paracentral opacity where preoperative imaging can demonstrate that the extent of the scar lies outside the laser delivery zone, the femtosecond laser can be used and the capsulotomy position, depth, and energy parameters modified to successfully perform a capsulotomy while avoiding the area of the corneal scar as delineated by intraoperative imaging. This may, however, limit the size of the capsulotomy, as in our case. Intraoperative modifications are required to overcome the error messages during femtosecond laser treatment. In conclusion, femtosecond laser–assisted cataract surgery may be a useful adjunct in cases with mature white cataracts and corneal scars that can be excluded from the laser delivery zone.
