    Keratometric changes in a population-based study: a comparative analysis of pre- and post-cataract surgery outcomes
    (Medip Academy, 2025-06) Ali, J; Khan, M; Khan, S; Gupta, SK; Saeed, A; Pant, K.
    Background: This study aims to evaluate the distribution of keratometry in cataract patients to know the variation in pre and post of small incision cataract surgery (SICS). To determine the variation in pre and post of small incision cataract surgery (SICS) using Bausch and Lomb keratometry instrument. Methods: This is a cross sectional study, undertaken at secondary centre of Dr. Shroff抯 Charity eye hospital Mohammadi. Two hundred patients will be selected for keratometry in pre and post of SICS. Small incision cataract surgery (SICS) will be done with straight incision with back cut technique using 1.5 mm incision from limbus and 6.0 mm optic PMMA IOL implantation. All surgeries will be performed by a single surgeon, surgical procedures being standardized. Results will evaluate at the end of the study. Results: Out of the total 200 patients 75 (38%) are male and 125 (63%) are female with the age Ranging from 40-80 years. The data are further divided into 2 subgroups (>50 and <50 years) and variations in pre and post of SICS are calculated for individual age Subgroups and gender. Out of total 200 patients in post op K1 reading subtraction the absolute variation value <=1.00 are found in 185 patients (92.50%) while the absolute variation value >1.00 are found in 15 patients (7.50%). In post op K2 reading subtraction the absolute variation value <=1.00 are found in 178 patients (89.00%) while the absolute variation value >1.00 are found in 22 patients (11%). Conclusions: Most frequently observed pre-existing corneal astigmatism in this study is the corneal astigmatism or absolute variation value in K1 are <=1.00D n 93% and >1.00D in 8%. And absolute variation value in K2 are <1.00D 89% and >1.00D 11%. The change in K reading are in males 38% and females 62% >50 years age group. On the other hand, the K reading are decreased to 35% in males in <50 years age group and increase to 65% in females in <50 years age group. As the age advances the astigmatism becomes more common which is more evident in females as compared to males. This can be easily corrected with appropriate measures like corneal relaxing incisions, excimer laser refractive procedures, femto laser assisted astigmatic keratectomy and toric IOL implantation.

    Premature presbyopia: causes, diagnosis, and management strategies - an overview
    (Medip Academy, 2024-06) Sonali, K. M.; Dubey, G.; Pant, K.; Tripathi, A.; Yadav, P.
    Premature presbyopia refers to the early onset of age-related vision changes typically associated with presbyopia, a condition characterized by the loss of near vision accommodation. This review article aims to provide an overview of the causes, diagnosis, and management strategies for premature presbyopia. The database collected from PubMed, PubMed Central (PMC), Cochrane library, and Google scholar and research gate. This review discusses the potential underlying mechanisms contributing to premature presbyopia, including genetic factors, environmental influences, and ocular conditions. Additionally, the diagnostic criteria and assessment methods used to identify premature presbyopia and differentiate it from other vision disorders. Finally, this review examines various management options for premature presbyopia, including corrective lenses, pharmacological interventions, surgical procedures, and emerging treatments. By understanding the factors contributing to premature presbyopia and implementing appropriate management strategies, healthcare professionals can effectively address the needs of individuals experiencing early onset age-related vision changes.
