2. TORIC ICL – REFRACTIVE OUTCOMES PURPOSE TO STUDY THE EFFICACY AND PREDICTABILITY OF THE FIRST 100 CONSECUTIVE TORIC ICL IMPLANTS

3. TORIC ICL – REFRACTIVE OUTCOMES MATERIALS & METHODS  NUMBER OF PATIENTS- 69 (MALE – 40, FEMALE - 29)  NUMBER OF EYES- 100 (UNILATERAL – 38, BILATERAL- 31)  AGE GROUP- 18 TO 48  PERIOD OF FOLLOW-UP - 2 TO 24 MONTHS  STUDY PERIOD- MAY 2007 TO DEC 2009

4. TORIC ICL – REFRACTIVE OUTCOMES INCLUSION CRITERIA  AGE ABOVE 18 YEARS WITH STABLE REFRACTION FOR ATLEAST ONE YEAR  NOT IN THE RANGE FOR LASER VISION CORRECTION  CORNEAL THICKNESS < 480 µ  RESIDUAL BED < 300 µ  ASTIGMATISM > 3 D  SPHERICAL EQUIVALENT > 12 D  ANY EVIDENCE OF FORME FRUSTE KERATOCONUS  AC DEPTH > 2.8 mm  OTHERWISE NORMAL EYES (MILD TO MODERATE MYOPIC MACULAR DEGENARATION NOT CONSIDERED AS AN EXCLUSION)

5. TORIC ICL – REFRACTIVE OUTCOMES PROCEDURE  SIZING BASED ON CALIPERS & ORBSCAN W to W MEASUREMENT  YAG IRIDOTOMY 1 WEEK BEFORE SURGERY  TOPICAL ANAESTHESIA  AXIS MARKING WITH PATIENT SITTING IN OPERATION THEATRE  TEMPORAL 3.2 mm INCISION

7. TORIC ICL – REFRACTIVE OUTCOMES POWER RANGE CORRECTED SPHERICAL RANGE- 1.50 TO – 19.00 CYLINDER RANGE- 1.25 TO – 5.5 SPHERICAL EQUIVALENT RANGE2.75 TO 20

8. TORIC ICL – REFRACTIVE OUTCOMES. RESIDUAL POWER IN SPH EQUIVALENT BETWEEN 0.25 & 0.521 EYES BETWEEN 0.5 & 13 EYES > 11 EYE

9. TORIC ICL – REFRACTIVE OUTCOMES RESIDUAL CYLINDER BETWEEN - 0.25 & - 0.52 EYES BETWEEN - 0.5 & - 1.09 EYES > - 15 EYES

11. TORIC ICL – REFRACTIVE OUTCOMES COMPLICATIONS  PIGMENT DEPOSITS ON ICL & ENDOTHELIUM : 31 EYES  POST OP RAISED IOP CONTROLLED WITH MEDICATION : 7 EYES  LOW VAULT : 8 EYES  EXCESSIVE VAULT: 4 EYES  REPEAT IRIDOTOMY IN POST OP PERIOD : 2 EYES  LOCALIZED ANTERIOR SUBCAPSULAR OPACITY : 1 EYE  ICL REPOSITIONING FOR INAPPROPRIATE AXIS : 2 EYES HIGH VAULT

12. TORIC ICL – REFRACTIVE OUTCOMES CONCLUSION TORIC ICL SEEMS TO BE A RELIABLE, PREDICTABLE MODALITY FOR CORRECTING MYOPIC ASTIGMATISM WHICH ARE NOT AMENABLE TO LASER VISION CORRECTION
