Abstract Details

Purpose:

To compare macular thickness after femtosecond laser assisted bimanual cataract surgery (FSL-BMICS) versus standard phacoemulsification bimanual microincision cataract surgery (B-MICS).

Setting:

Institute of Ophthalmology, University of Modena and Reggio Emilia, Modena, Italy (Head: Prof. Gian Maria Cavallini).

Methods:

Prospective observational case series study to evaluate retinal macular thickness (CMT) in two groups of patients who underwent uncomplicated FSL-BMICS (Group A, 70 eyes) and standard phacoemulsification B-MICS (Group B, 70 eyes). Both groups were comparable for all preoperative variables. Exclusion criteria were any ocular pathology occurred before and after cataract surgery. CMT was evaluated by spectral domain OCT preoperatively and at 7, 30, 90 days, 3 months, 6 months, 12 months after surgery.

Results:

Mean EPT was 5.05±3.32sec in Group-A and 3.81±1.18sec in Group-B. Mean Total Surgical Time: 18.03±4.16min in Group-A; 12.62±4.37min in Group-B. Mean BCVA improvement at 6 months was 0.399±0.252LogMar in group-A(p<.05) while it was 0.448±0.232LogMar in group-B(p<.05). CMT was 210.46±24.77micron in group-A and 196.57±45.27 in group-B at 6 months after surgery. In both groups we found a statistically significant increase in CMT at 6 months follow-up (p<.05). Moreover, we found a statistically significant higher CMT in group-A in the follow-up if compared with group-B (p<.05). In group we found 3 cases of pseudophakic cystoid macular oedema.

Conclusions:

These datas showed higher CMT in the FSL group after adjusting for age and preoperative thickness across the whole time course, with no clinical influences on BCVA. According to the literature, this was probably due to a higher inflammation caused by a significantly greater concentration of intraocular prostaglandins produced by the FSL microplasma of gas.
