Abstract Details

Purpose:

Primary posterior circular curvilinear capsulorexis (PCCC) during cataract surgery is an effective method to reduce the risk of secondary cataracts. Its creation is relatively simple and safe, however, breaking of the barrier between the lens capsule and the vitreous compartment is theoretically higher risk of thickening the macular region or macular edema (CME).

Setting:

SOMIC, Eye center, Karlovy Vary Czech Rep. Opthalmology dep., Vinohrady Teaching Hospital, 3rd. Faculty of Medicine, Charles University, Prague

Methods:

Prospective, randomized trial. 15 patients (30 eyes) with simultaneous bilateral cataract surgery, randomly one eye was performed PCCC (group 1), on the other eye the capsule was intact (group 2). Postoperatively, patients received topical antibiotic and non-steroidal anti-inflammatory drug for 3 weeks. After surgery (1 and 3 months) the visual acuity and macular thickness on OCT  were evaluated - central retinal thickness (CRT) and central retinal volume (CRV).

Results:

In group 1(PCCC) the mean CRT preoperatively was 277.9±19.6µm and the CRV was 0.217±0.015mm. One month after surgery, the mean CRT was 284.5±20.0µm and CRV was 0.223±0.017mm3. The UDVA was 0.91±0.37. 3 months after the surgery, CRT was 283.9±20.0µm and CRV was 0.222±0.015mm3. In group 2, the CRT preoperatively was 275.3±17.6µm, the CRV was 0.218±0.015mm3. One month after CRT was 283.3±18.3µm, CRV  0.223±0.014mm3, UDVA 0.91±0.28. 3 months after the surgery the mean CRT was 281.2±18.8µm and CRV was 0.221±0.014mm3.

Conclusions:

There was no statistically significant difference in mean CRT or CRV in both subgroups either one month or 3 months after surgery. CME was not recorded. We concluded that the uncomplicated PPCCC is a safe surgical method for preventing secondary cataract.
