A Study of Anatomical and Visual Outcome in Secondary Scleral Fixated Intra-Ocular Lens Implantation

Aims: To study of anatomical and visual outcome in secondary scleral fixated intra-ocular lens implantation Settings and Design: Hospital based prospective case study conducted at a tertiary care centre over a period of 2 years. Methods and Material: 30 eyes of 30 patients underwent secondary scleral fixation of IOL by 2-point Ab-externo technique. Post-operatively best corrected visual acuity, IOP, Keratometry and complications encountered were noted at regular follow-up of 7th day, 6 weeks, 3 months and 6 months. Results: Mean age of patients in the study was 52.33 years in the range of 46-60 years. Out of the 30 cases, 56.66% were men and 43.33% were women. Best corrected pre-operative V/A was in the range of 6/24 to 6/18 (53.33%), 6/12 to 6/9 (16.66%), 6/60 to 6/36 (30%). At final follow-up of 6 months, the results were, 63.33% in range of 6/12 to 6/9, 26.66% in 6/24 to 6/18 and 10% in 6/60 to 6/36. In early complications, transient corneal oedema was seen in 20%, transient IOP elevation in 10%, while vitreous haemorrhage and post-operative hyphaema was noted in 3.33% each. In late complications, Cystoid Macular Oedema was seen in 10%, pupil distortion was seen in 6.66% of patients and decentred IOL was seen in 3.33% of the patients. Conclusion: Secondary scleral fixated IOL provides good visual outcome and better anatomical position with minimal complications.
