The Influence of Pupil Dilation on Predicted Postoperative Refraction Calculated by Using Third and Fourth Generation Calculation Formulas in Pre-Presbyopia Patients
The goal of this study is to assess the effect of pupillary dilation on predicted post-operative refraction (the Plano or least minus refraction) and on recommended intraocular lens (IOL) power calculated by using the third generation and fourth generation formula to measure the difference betwee...

| description | The goal of this study is to assess the effect of pupillary dilation on predicted post-operative refraction (the Plano or least minus refraction) and on recommended intraocular lens (IOL) power calculated by using the third generation and fourth generation formula to measure the difference between pre and post pupil dilation on ACD. This study included 40 eyes with cataract will undergo phacoemulsification and divided into two group Group (A): 20 cataract patients with biometry by third formula (SRK/T and Hoffer Q). Group (B): other 20 cataract patients with biometry by fourth formula (Holladay 2). There were statically non-significant differences found between PPR before and after pupil dilation in Group A and Group B with p value 0.861and 0.181 respectively. The main age of our patient in group A ranged from (21 – 42) years and age ranged from (25 to 45) in group B with statically non-significant differences between two groups. |
