| Title | Evaluation of Femtosecond Laser-Assisted Cataract Surgery compared with Conventional Cataract Surgery |
| Abstract Nr. | 1057 |
| Purpose | To investigate the efficacy of the LenSx® femtosecond (FS) laser-assisted cataract surgery compared with conventional cataract surgery. |
| Methods | This retrospective study included patients with nuclear lens opacities who underwent a cataract surgery between April 2014 and June 2014 by one single experienced surgeon (MH). We measured pre - and postoperatively at 1 month the best-corrected visual acuity (BCVA), automated keratorefractometry, intraocular pressure (IOP) and corneal endothelial cell count (ECC) . We compared the BCVA, IOP, ECC , effective phaco time (EPT) and cumulative dissipated energy (CDE) between both groups with a t-test. |
| Results | We included 57 eyes of 41 patients in the conventional group and 41 eyes of 28 patients in the FS laser group. The mean EPT en CDE in the conventional group was 0.95 ± 0.95 and 9.91 ± 3.22; and in de FS group 0.74 ± 1.62 and 6.7 ± 3.9 respectively (p: 0.33; p: 0.00004). The mean IOP lowering 1 month after surgery was in the conventional group 2.3 ± 2.9 mmHg and in the FS group 3.01 ± 2.3 mmHg (p: 0.2). The pre-and postoperative BCVA was comparable in both groups. There was a decline of more than 5% ECC in 33% of the patients in the conventional group and 38 % in the FS group (p:0.35). Seven of the 41 eyes had a tag after capsulorhexis made with the LenSx®. In the FS group, 2 eyes had postoperative wound leakage 1 day after surgery compared to none in the conventional group. |
| Conclusion | The femtosecond laser is an effective and safe technique in cataract surgery. There was no difference in final BCVA in both groups. There was a significant reduction in the CDE in the laser group. No significant difference in reduction of ECC was seen between the two groups. |
