Abstract Details


To evaluate the degree of pupil diameter changes after femtosecond laser emission during femtosecond laser-assisted cataract surgery (FLACS).


S.N. Fyodorov MNTK “Eye Microsurgery Complex”, Cheboksary branch, Russian Federation.


Forty eyes of 40 patients underwent FLACS. Patients mean age was 68.21±13.21 years (from 54 to 86 years). During the preoperative preparation every patient was instilled by antibiotic, antiseptic, nonsteroidal anti-inflammatory and mydriatic eye drops 20 minutes before the operation. First step of FLACS was performed on the LenSx laser system (Alcon, USA), second step – the phacoemulsification was performed on the Infinity vision system (Alcon, USA). Spherical IOLs MIOL-2 (Reprer-NN, Russia) were implanted to all patients. Before the first step start and after its end pupil diameter was measured by the interface of LenSx laser.


No complications were detected during the operation and in postoperative period. Mean size of pupil diameter before the first step of FLACS was 6.78±0.93 mm (from 4.7 to 8.0 mm). After the first step the mean size of pupil diameter was 6.74±0.97 mm (from 5.0 to 8.2 mm) (p=0.65).


Use of nonsteroidal anti-inflammatory drugs with mydriatic during preoperative preparation allows to get a persistent mydriasis and lowers the risk of getting miosis after femtosecond laser emission during FLACS.
