Abstract Details

Purpose:

To evaluate the effect of fludicities paramters changs during phacomeulsifications on postoperative outcome in different nuclear densities

Setting:

North american LASIK and eye surgery center, Dubai, UAE

Methods:

This study included 50 eyes (50 patients) with age-related Patients with nuclear sclerosis grades 2 and 3 as per the LOCS III classification were included. Exclusion criteria were: presence of glaucoma, shallow anterior chamber (ACD < 2.1 mm), pupillary dilatation < 6 mm, extremely soft or dense cataracts (grades 1, and > grade 4 according to the LOCS III classification), posterior polar cataract, subluxated cataract, white mature cataract, diabetic retinopathy, high myopia (defined as AL > 25 mm), uveitis, or previous ocular trauma. The patients were assigned to Group 1(low fluidic parameters: (LFP) Aspiration flow rate(AFR) 20cc/min; bottle height(BH) 90 cm; vacuum 400 mm Hg) or Group2(high fluidic parameters: (HFP) AFR: 40cc/min, BH: 110 cm; vacuum 400 mm Hg). Postoperatively, rate of change in central corneal thickness(CCT) at days 1 and 7, endothelial cell density(ECD) at 3 months, anterior chamber inflammation on days 1 and 7 and corneal clarity on day 1 were compared

Results:

Group 1 comprised 25 eyes (LFP) and Group 2 another 25 eyes (HFP). The postoperative increase in UDVA and CDVA was statistically significant in both groups (P<.05). No intra or postoperartive complications were recorded There were no significant differences between the 2 groups regarding the change of UDVA, CDVA, refractive error reduction (P>.05). Rate of change in CCT was greater in Group 2 at postoperative days 1 and 7 (P< 0.001).Anterior chamber inflammation and corneal clarity at 1 day were significantly better in Group 1.

Conclusions:

Higher aspiration flow rate and bottle heights are associated with higher anterior chamber imflamations and more edematous cornea postoperatively FINANCIAL INTEREST: NONE
