ROME — A phakic implantable Collamer lens can be an option for the correction of compound and myopic astigmatism in eyes with subclinical or stabilized keratoconus, also following cross-linking treatment, according to one surgeon.

"I trust this lens (ICL, STAAR Surgical). It is quite a straightforward procedure for experienced surgeons, and I use it now quite routinely in these eyes with rewarding results," Vikentia Katsanevaki, MD, said at the International Society of Refractive Surgery symposium hosted by the Italian Society of Cataract and Refractive Surgery.

The outcomes of ICL implantation were shown in a series of 50 eyes of 26 patients. Mean attempted correction was -8.35 D, ranging between +2 D and -17 D. Mean best corrected visual acuity was 20/40 or better.

"At 1 year, these patients had set around 0 D. More than 40% had gained two or more lines of BCVA, and in 30%, uncorrected vision after surgery was better than best corrected vision before surgery," Dr. Katsanevaki said.

In her early series, Dr. Katsanevaki had no cases of ICL-induced cataract. Although cataract rate with the new generation of ICLs is much lower, she expects a few cases within the next 4 years to 5 years.

"However, this is a complication I can deal with and a risk I can accept better than the risk of endothelial decompensation with anterior chamber phakic lenses," she said.
