PURPOSE : To evaluate the results of small incision cataract surgery
with intraocular lens implantation using Prechop Manal Phacofragmontation
techinque (Prechop
MPF) performed from April 2000 through May 2003
SETTING : Department of ophthalmology,Prapokklao
Hospital , Chantaburi ,Thailand.
DESIGN : Interventional case series.
METHOD : A Retrospective study was performed of
all 339 consecutive patients who underwent
extracapsular cataract
extraction using prechop MPF technique.Data included are preoperative
and postoperative best corrected-visual
acuity, intraoperative and postoperative complications
and postoperative astigmatism.The
patients were examined preoperatively and 1 day and 1, 3, 6 months
postoperatively.
RESULTS
Of 339 eyes ,best corrected visual acuity
of 20/40 or better was achieved in 223 eyes(65.78%)
and of 20/20 or better
in 154 eyes ( 45.43 %) at the end of first postoperative week.
The most frequent intraoperative
complication was posterior capsule rupture ( n = 8 ) . In all cases of capsule rupture , a posterior
chamber IOL was implanted in the sulcus.The significant postoperative
complication was transient corneal edema , which developed in 29 eyes ( 8.55 %)
No permanent complications
(e.g. corneal decompensation ) occurred in any case . The mean preoperative astigmatism was 0.53
diopter(D) +/- 1.17 (SD) and at one month postoperatively , the
mean astigmatism was 0.18 +/- 1.61D.
Simple subtraction
analysis of preoperative and
1 month postoperative keratometry
showed that the mean
induced astigmatism was 0.34 +/- 1.43 D.
CONCLUSION
Small incision cataract extraction using
PrechopMPF technique is safe , economical and dose not require expensive instrumentation.
