Femtosecond laser assists bag-in-the-lens IOL insertion technique

SAN FRANCISCO — A stumbling block to inserting a bag-in-the-lens IOL may be overcome with the use of a femtosecond laser, according to a presenter here.
The original bag-in-the-lens IOL insertion technique, which is not approved by the U.S. Food and Drug Administration, was designed to prevent posterior capsule opacification in pediatric and adult cataract patients, Ana Paula Canto, MD, said at the American Society of Cataract and Refractive Surgery meeting. However, the technique for bag-in-the-lens IOL insertion is considered difficult because centration depends on an appropriately sized and centered capsulorrhexis.
"And, the posterior continuous curvilinear capsulorrhexis has been criticized as too difficult to routinely manually perform," she said.
Canto and colleagues followed up 31 patients who underwent bag-in-the-lens IOL implantation using a technique that created both anterior and posterior capsulotomies using the Catalys femtosecond laser (OptiMedica).
At 1 month, there were no preoperative or postoperative complications, no vitreous loss, no increased IOP, no negative dysphotopsia, no posterior capsule opacification and no retinal detachment, she said.
Studies with a larger number of patients and long-term follow-up are necessary to evaluate the final refractive outcomes and possible adverse effects, she said.
Disclosure: Canto has no relevant financial disclosures, although coauthors H. Burkhard Dick, MD, and William W. Culbertson, MD, are members of the medical advisory board of OptiMedica.
