Abstract Details

Purpose:

White Mature Cataracts (WMC) are commonly seen in developing world due to late presentation. Phacoemulcification of WMC are challenging and often perform under local anaesthesia. Most challenging step of WMC is the capsulorrhexis due to high intralenticular pressure which could be further aggravated with local anesthesia. Topical anesthesia will eliminate the extra pressure developing in the lens due to anesthesia. This is to evaluate the outcome and surgical complicatins of phacoemulcification (Phaco) done on WMC with Topical and Intracameral Anaesthesia

Setting:

Eye Unit, General Hospital, Polonnaruwa, Srilanka

Methods:

Retrospective analysis of data of all WMC performed under Topical and intracameral anaesthesia from October 2013 to February2014. Patient demographics, surgical complications, necessity of any supplementary anesthesia and post operative visual out come were evaluated. Surgery was started with topical anesthesia and intracameral anesthesia was introduced after the main phaco incision. Capsule stained with Trypan Blue and Capsulorrhexis done with cystitome under dispersive viscoelastic cover. Routine phaco done using straight vertical chop technique and intracameral moxifloxacin infused at the end.

Results:

Total 164 eyes of 164 patients and 91 were females. Majority of patients (109) were between 51-70 age group. 09 patients had extended capsulorexis but successful phacoemulcification were performed on 08 patients with 07 had intra bag lens implantation. Two patients needed single port pars plana anterior vitrectomy. Only Eight of 164 (4.87 %) eyes needed supplementary anesthesia using subtenon anesthesia while performing the surgery. Best corrected visual acuity on follow up was 6/12 or better in 137 eyes (83.5%)

Conclusions:

Phacoemulcification of white cataracts are challenging but it could be safely handled with Topical and intracameral anesthesia. Most pronounced complication was extension of capsulorrhexis . Comparative study between phaco on WMC with Topical and Local anesthesia would be further useful FINANCIAL INTEREST: NONE
