Abstract Details

Purpose:

To assess the utility of nonsteroidal antinflammatory drug (NSAIDs) before femtolaser assisted cataract surgery (FLACS) in order to avoid the induced myosis. The use of FLACS is effective for the partial fragmentation of the lens nucleus, capsulorhexis and corneal incisions prior to cataract surgery. We have occasionally observed a treatment-induced myosis after FLACS.

Setting:

Hospital Universitario de San Juan de Alicante, Spain

Methods:

This prospective clinical study included 61 eyes undergoing cataract surgery with FLACS. Eyes were randomly assigned to 2 groups, one of the group received Ketorolac 0.5% drops (Acular®, Allergan) three times before FLACS. The other group did not recieved Ketorolac. Both groups were treated with ciclopentolate 1% (Cicloplejico®, Alcon) and tropicamide 1% (Tropicamida®, Alcon) as midriatic drugs. In all patients pupil diameter was measured using IOL Master 700 (Zeiss) just before FLACS and ten minutes after the procedure. For FLACS, LenSx (Alcon) was used: 5.5 mm capsulorhexis and one cross pattern for facofragmentation.

Results:

Both groups were similar previous to procedure: similar intraocular lens power, axial length, anterior chamber length, corneal astigmatism and medium keratometry. The 30 eyes of group 1 (NSAIDs group) show a medium size of pupil of 7.03 before surgery, while in the group 2 (31 eyes, no NSAIDs) it was 6.82. After FLACS, the medium pupil size were 6.62 and 6,16 respectively. The difference in induced myosis was statistically significant (p=0.03). We did not found any induced secondary effect because of NSAIDs.

Conclusions:

The use of ketorolac 0.5% drops three times previous to FLACS has shown to avoid the myosis induced by the laser treatment, reaching a very stable pupil size ten minutes after the procedure. In view of these results, we highly recommend the use of ketorolac 0,5% three times before FLACS with LenSx.
