Abstract Details

Purpose:

Analysis of results of ND:YAG-laser capsulotomy of posterior capsule opacification (PCO) in patients with intraocular correction of aphakia by PTHIOL (open-bag device) in following aspects: the characteristics of ND:YAG-laser capsulotomy at PTHIOL close contact with the posterior lens capsule, safety and efficacy of the laser surgery, the capsulotomy impact on PTHIOL position.

Setting:

Department of Ophthalmology, Penza Federal State Institute for Postgraduate Medical Studies of the Ministry of Health of Russian Federation, Penza, Russia.

Methods:

PTHIOL MIOL-28 5,5x15,5x0,2 mm ('Reper-NN', Ltd.) was implanted on 265 eyes of 218 patients after non-complicated PHACO through 2.2-mm incision . ND:YAG-laser capsulotomy was performed on 11 eyes of 10 patients (4.15%) in follow-up of 4.5 to 8 years. Indications for capsulotomy were significant visual acuity (VA) decrease and retinal reserve presence. Capsulotomy was performed in a circle or a cross forming 4-mm hole in borders of PTHIOL optical part. Pre- and postoperative examination includes refractometry, determining of retinal reserve and monitoring of PTHIOL position by UBM-biometry before and after the capsulotomy in follow-up of 7 months to 3.5 years.

Results:

All capsulotomies performed in one session by 12-28 pulses of power of 0.8-0.9 mJ and were non-complicated without PTHIOL optical part damage. VA with correction was 0.2-0.6 (average 0.42±0.03) pre-op and 0.5-1.0 (average 0.71±0.04) on the 5th day post-op wherein VA increase occurred in all cases and accordingly to retinal reserve. PTHIOL position after capsulotomy was correct and stable. It was no significant difference according to UBM biometrics in the pre- and postoperative PTHIOL position. In remote follow-up any changes in the laser capsulotomy holes diameter weren’t marked and clinical refraction and PTHIOL position also were stable.

Conclusions:

1. PCO development requires capsulotomy was observed in 4.15% of patients in follow-up to 8 years after PTHIOL implantation, that indicate the implant effectiveness in PCO preventing. 2. ND:YAG-laser capsulotomy at PCO in patients with intraocular correction by PTHIOL is safe and effective. 3. ND:YAG-laser capsulotomy within the borders of PTHIOL optical part, as the lens material hydrophobicity and a large area of contact of the implant with capsular bag are the factors prevented the violation of PTHIOL position and other complications in this group of patients.
