Abstract
Purpose - This study aims at analyzing the visual and refractive outcomes following simultaneous phacoemulsification and pterygium excision with conjunctival autograft (CAG). Setting-Tertiary eye care hospital in South India. Design-Retrospective study. Methods-508 eyes that underwent simultaneous phacoemulsification with pterygium excision between 2011-2017 were included in the study. Exclusion criteria-Pre-operative astigmatism of > 2 D, grade 3 pterygia, recurrent or double head pterygia, traumatic or complicated cataract. Pre-operative evaluation-clinical examination, keratometry, IOL power calculation, retinoscopy and subjective refraction. Procedure-Phacoemulsification with foldable monofocal IOL followed by pterygium excision with conjunctival autografting using tissue glue. Post-operative follow up-Periodically up to 6 months. Results- Mean pre-operative best corrected visual acuity (LogMAR) was 0.41+/-0.46 with post-operative mean being 0.04+/-0.12 (p=0.001). Mean pre-operative and post operative astigmatism were -1.25+/-0.60 D and -0.73+/-0.58 D (p=0.001) respectively. Mean post-operative myopic spherical error was -0.85+/-0.48 D. 34.33% of the patients had a post-operative refractive error out of which 87.42% had myopia and 12.57% had a hypermetropic error (<1D). 63.27% of the eyes with myopic error had an error of < 1 D. Most commonly seen complication was sub conjunctival haemorrhage followed by graft retraction in 12 and 10 eyes respectively. Conclusion- The combined single step procedure of phacoemulsification with pterygium excision in indicated cases, is safe and effective with good visual outcomes. The post-operative myopic residual error can be anticipated and reduced by slightly under correcting the IOL power in patients with concurrent pterygium to optimize the visual outcome.
