| Comparator Agent |
Cataract extraction plus monofocal intraocular lens implantation under general anaesthesia (Group B) |
general anaesthesia All cases of bilateral developmental cataract will be assessed, and based on the inclusion and exclusion criteria, they will be enrolled for the study. Using block randomization and computer generated numbers, patients will be divided into 2 groups. Group A: 20 patients will be assigned to Group A for whom Enhanced Monofocal IOL (Tecnis Eyehance, ICB00) will be inserted Group B: 20 patients will be assigned to Group B for whom Monofocal IOL (Tecnis Monofocal, ZCB00) will be inserted. Patients with Delta TK more than 1 D, Toric Monofocal IOL/Toric Enhanced Monofocal IOL will be placed. Preoperative workup will done (refer to the attached preoperative proforma for details). The IOL power will be calculated using Barrett’s Universal Formula using IOL Master 700 and the first residual myopic power will be selected as the power of IOL for implantation. Lens aspiration will be done using the Centurion Phacoemulsification System (CPS). Both eyes shall be operated within a week’s time and the patient shall be evaluated on post-operative day 1. Suture removal shall be done after 1 month. Post-operative evaluation for the study shall be conducted after 1 month, 6 months and 12 months |

Brief Summary
|
Visual rehabilitation for near is important for children undergoing cataract surgery due to increased demands for near work. The compliance for glasses and post-operative follow-ups in children is generally sub-optimal in developing countries. Multifocal IOLs are a good option for rehabilitation of unaided near vision, however they are associated with post-operative glare, halos and dysphotopisa and may not be suitable for eyes which may potentially grow in axial length. Enhanced monofocal IOLs may potentially provide better binocular uncorrected near to intermediate visual acuity due to their extended range of focus as compared to standard monofocal IOLs with comparable photic phenomenon. This trial aims to study the optical performance of enhanced monofocal IOL versus standard monofocal IOL in pediatric age group with respect to binocular uncorrected near visual acuity. Secondarily, this trial will also compare the uncorrected and best-corrected distance and intermediate visual acuity, subjective refraction and acceptance, HOA, stereopsis (distance and near) and contrast sensitivity, need for near aid between the two groups. |
