Objective: To evaluate the visual outcome and complications of the small incision cataract surgery with foldable intraocular lens implantation using the Kongsap technique.
Study Design: Prospective, non-comparative study.
Material and Method: This prospective study was conducted at Prapokklao Hospital, Chanthaburi between December 2005 and May 2006. The ninety-five eyes of 95 patients underwent cataract surgery using the Kongsap technique. The best corrected visual acuity, intra-operative and post operative complications, and the corneal endothelial cell loss were then evaluated. Follow-up visits were scheduled at one week, one month, three months, and six months.
Results: Best corrected visual acuity(BCVA) was 20/40 or better in 83 eyes (87.37%) at one week postoperatively, in 86 eyes (90.53%) at one month, in 87 eyes (91.58%) at 3 months, and in 85 eyes (89.48%) at 6 months. The most common intra-operative complication was iris prolapse (7.37%). Other intra-operative complications were posterior capsule rupture (2.11%), transient intracameral bleeding (2.11%), and capsulorhexis tear (2.11%). The most significant post operative complication was transient corneal edema located at the corneal wound, which developed in seven eyes (7.37%). No other significant complications were noted during the six- month follow up period. Mean endothelial cell loss was 5.3% at one month and 7.1% at three months post operatively.
Conclusion: Manual sutureless cataract surgery with foldable intraocular lens using the Kongsap technique when performed by an experienced surgeon was a safe procedure with good visual recovery and no need for a phaco machine.
