Tapunya M Background: Question of different techniques of cataract surgery would offer different post-operative visual
acuity (VA) has been asked.
Objectives: To compare the pre-and post-operative VA of cataract patients operated by different techniques as
Extracapsular Cataract Extraction(ECCE), Phacoemulsification(PE), and Manual Phaco Fragmentation
(MPF) and compare in different age groups.
Method: The post-operative visual acuity of cataract patients was collected from 72 hospitals in Bangkok and
rural part of Thailand. Techniques of cataract surgery were recorded. The cases with pre-operative and intraoperative
complication and cases operated without intraocular lens (IOLs) implantation were ruled out.
Results: VA of cataract patients post-operation was statistically significant better than pre-operation at p–
value (less than 0.05) and the result persisted for every age group. Cataract patients operated by PE had
better post-operative VA than patients operated by ECCE and MPF, even if MPF had the best post-operative
VA. This is because the total cases were less than the other procedure.
Conclusion: Due to the nature of retrospective study, the cause of poor post-operative VA was due to astigmatism.
The pre-operative astigmatism was not recorded thus preventing a complete analysis.
