1 Comparison of Visual Outcomes With Toric IOL and With Limbal Relaxing Incisions in Cataract Surgery Eriko Fukuyama, MD Fukuyama Eye Clinic Fukuoka, Japan The author has no financial interest in the subject matter of this e-poster.

2 Purpose To compare cylindrical changes between a toric intraocular lens (IOL) and limbal relaxing incisions (LRIs) to correct preexisting astigmatism in patients underwent cataract surgery.

3 Patients We prospectively reviewed the medical records of 20 patients who underwent primary cataract surgery for bilateral cataract with corneal astigmatism 1 dioptor and over at Fukuyama Eye Clinic from August 2009 to August 2010. They underwent implantation of a AcrySof IQ Toric IOL in one eye (group A) and with implantation of a AcrySof IQ IOL with LRIs in a fellow eye (group B). Mean age :75.5±5.6 Male : Female= 15 : 5

4 Group A : Incision: Coaxial MICS (2.4mm) IOL: ACRYSOF ® IQ Toric aspheric IOL Group B : LRIs: Fukuyama LRI Nomogram, 1 Pair Incision: Coaxial MICS (2.4mm) IOL: ACRYSOF ® IQ aspheric IOL Surgical Methods

5 Results The mean corneal astigmatism measured by keratometer before the surgery was 1.89 dioptors in group A and 1.73 dioptors in group B. After the treatment, the mean corneal astigmatism was 1.89 dioptors in group A and 0.81 dioptors in group B, and the mean refraction astigmatism was 0.73 dioptors in group A and 0.51 dioptors in group B at six months after the surgery. The UDVA and CDVA were similar in both groups. The corneal shape measured by topography was stabilized earlier in group A than in group B.

6 Change in Corneal Cylinder (Keratometory) D ** Post-Op (n=20) ** : Wilcoxon rank-sum test P Value<0.02

7 Change in Refractive Cylinder D ** : Wilcoxon rank-sum test P Value: 0.0034 ** Post-Op (n=20)

8 Induced Corneal Cylinder (via Topography) Post-Op Change in induced corneal cylinder (D) (n=20)

9 Change in Corneal Cylinder (Keratometory) Corneal cylinder (Pre-Op) T-IOL LRI s ( D) (n=20) Corneal cylinder (Pre-Op) Corneal cylinder (Post-Op 6 Months Corneal cylinder (Pre-Op)

10 T-IOL LRI s ( D) (n=20) ( D) Refractive cylinder (Post-Op 6 Months Corneal cylinder (Pre-Op) Change in Refractive Cylinder

11 Comparison of Toric IOLs with LRIs LRI Toric IOL High-precision correction △ ○ Stability of Refraction △ ○ Early restoration of VA △ ○ High-order aberration △ ○ Asymmetric astigmatism ○ △ Complication: over collection rare none Complication: Irregular astigmatism rare none

12 Conclusion Both a toric IOL and LRIs are useful to correct preexisting astigmatism in patients having cataract surgery. A toric IOL excels LRIs in the early stabilization of the corneal shape.
