DETERMINANATS OF VISUAL OUTCOMES AFTER PHACOEMULSIFICATION CATARACT SURGERY IN PATIENTS WITH NO OCULAR COMORBIDITY

DR KHUSHBU SHETHH V DESAI EYE HOSPITALPUNE

INTRODUCTION Cataract surgery is considered as a

refractive surgery in today’s time. The aim is to give minimum post operative

refraction. Role of biometry is critically important. The commonest cause of poor patient

satisfaction is poor UCVA. In today’s age success of a private practitioner is measured by the vision obtained in the patient.

We need to know about determinants of poor post operative outcome.

Our study tries to address this issue.

Aims and objectivesAim : To identify reasons for refractive

surprise

Objectives :To identify patients who have less than targeted spherical equivalent and correlate them with

1)Surgical variables(cataract grade,anesthesia type,IOL type,Intraoperative complications)

2) Biometry variables ( scan type) 3)Spectacle variables (Cader of surgeon)

Methodology The study was conducted from july 2015 to june

2016 at H V Desai eye hospital, Pune. All patients with uncomplicated cataracts with no

ocular co morbidity were included in the study. Study includes 500 patients,46 patients were

excluded with other co morbidities.

Randomization-divided randomly using random number tables

Approval- institutional ethical and scientific committee approval was obtained.

DISCUSSION

We have studied various surgical and spectacle variables responsible for UCVA (Uncorrected visual acuity) less than 6/18.

BCVA (Best corrected visual acuity) measured in patients improved more than 6/18 (93.39%) who have UCVA less than 6/18

Post operative astigmatism is most important factor for less UCVA

POST OPERATIVE ASTIGMATISM FOR BCVA IMPROVING MORE THAN 6/18

CONCLUSION

Improving incision site ,using of optic scan type and toric IOLs reduce postoperative astigmatism and better Uncorrective visual acuity.
