Iris diaphragm stability during femtosecond-laser assisted cataract surgery with various preoperative non-steroidal anti-inflammatory drugs instillations

Purpose. To compare the efficacy of two different nonsteroidal anti- the conventional phacoemulsification (CPE) was performed using the inflammatory drugs for maintenance of intraoperative mydriasis and to same preoperative instillations. Pupil diameter was registered at 5 surgical define causative factors for laser-induced miosis. steps before FLACS (first pupil diameter – I∅), before phacoemulsification Material and methods. The prospective single center investigation (II∅), after viscoinjection (III∅), at А/I of the lens cortex (IV∅), at the end included the groups I and II (35 and 30 eyes) where femtosecond laser- of the surgery (V∅). Pupil diameter was calculated in the Image J program assisted cataract surgery was carried out with bromfenac 0.09% and version 2.0. Correlation analysis was performed by uniting the groups I indomethacin 0.1% instillations. In the groups III and IV (28 and 34 eyes) and II between intraoperative parameters and pupil diameter.Results. The second degree clinical significant miosis (CSM 2) (postcapsulotomy margin of the capsule was under the iris) was detected in one patient of the group I. In the group II – 5 patients had CSM 2 on the different steps of FLACS, the smallest diameter was 4.0 mm (one case – IV∅ and one –V∅).There were correlations between II∅ with IOP measured after 15 minutes (r=-0.42, p
