Background: To assess the results of femtosecond laser use in harder brown cataracts and share the first time experience.

Methods: Thirty eyes of thirty patients were included in this hospital based cross sectional descriptive study. The study was carried out from April, 2012 to July, 2012 in University of Bochum, Vision research center, Germany. All surgeries were performed by a single surgeon (Burkhard Dick) using the Catalys femtosecond cataract laser (Optimedica; Santa Clara, California) and a standardized “stop and chop” phaco technique with the Stellaris (Bausch + Lomb; Rochester, New York) phaco machine in venturi fluidics mode. Relevant data was entered in a proforma designed for the study and interpreted.

Results: In the study, 19 (63.3%) of the patients were females followed by males. The mean age of the patients was 74.83 years (Std. deviation 6.56). According to lenticular opacification classification system III (LOCS III); mean nuclear sclerosis was 3.9 (Std. deviation 0.80), mean absolute phaco time (APT) was 0.19 seconds (Std. deviation 0.24 seconds) mean effective phaco time (EPT) was 0.02 seconds (Std. deviation 0.04) and mean phaco power (MPP) used was 9.26% (Std. deviation 8.24). Amongst complications; remnant of anterior capsular tag and posterior capsular rupture (PCR) was noted in two patients respectively.

Conclusion: This study demonstrated that, with further innovation and optimization of technique and instruments femtosecond laser-assisted cataract surgery will become phacoless (“aphaco”) for most cataracts, whereas dense cataracts may still require the “pauci-phaco” (reduced phaco energy) technique.
