Abstract Details


Femtosecond laser assisted cataract surgery (FLACS) provides properly sized, perfect circular and centered capsulotomy. Contraction of the anterior capsule opening has been one of the common complications after cataract surgery. We evaluated reduction of anterior capsule opening area during 6 months after FLACS with hydrophilic acrylic intraocular lens (IOL) implantation.


Department of Ophthalmology, Tokyo Dental College Suidobashi Hospital.


This retrospective study included 56 eyes of 36 Japanese patients (59.8±10.9 years) who underwent FLACS with hydrophilic acrylic IOL (PODFT, PhysIOL) implantation in the capsular bag. LenSX® version2.23 (Alcon) was used for anterior capsulotomy, lens fragmentation, and corneal incisions. One week and 1, and 6 months after surgery, anterior segment images were captured under retroillumination after pupillary dilation. The area of anterior capsule opening was measured using Image J software with reference of the diameter of diffractive zone 1. The reduction rate from 1 week was calculated 1 and 6 months postoperatively.


The anterior capsule opening area 1 week and 1, and 6 months after surgery were 23.13±2.50, 21.41±4.64, and 20.62±5.38mm². The reduction rate 1 and 6 months postoperatively were 8.38±17.63%, and 10.91±20.99%, respectively. Over 20% of the reduction were found in 11 eyes (26.2%) 6 months postoperatively, which had no predisposing factors of anterior capsule contraction. Extraordinary contractions were observed binocularly in a patient (50.7% and 89.2%), and a neodymium:YAG (Nd:YAG) anterior laser capsulotomy and manual peeling of the fibrotic membrane were performed, respectively.


Postoperative reduction of anterior capsule opening area after FLACS were not significantly different compared with the results in manual cataract surgery and hydrophobic acrylic IOL implantation.
