The primary aim of the study is to investigate the correlation between preoperative hemodynamics and frailty scores in patients undergoing cataract surgery under general anesthesia. The secondary objective is to explore the relationship between preoperative and postoperative intraocular pressure changes and frailty scores.

Cataract stands as a significant cause of vision impairment worldwide, notably prevalent among the elderly. This study aims to explore the changes in intraocular pressure (IOP) and blood pressure under general anesthesia during cataract surgery in frail geriatric patients. The research emphasizes the critical role of frailty assessment in determining surgical risks among elderly surgical patients. It focuses on the hypothesis that frail individuals undergoing cataract surgery under general anesthesia might experience more pronounced effects on IOP and blood pressure during the surgical procedure compared to prefrail counterparts. This study emerges as a crucial step in understanding the impact of preoperative frailty assessment on surgical planning and outcomes.

Inclusion Criteria:

• 65-85 age
• ASA I-III
• cataract surgery with genel anesthesia

Exclusion Criteria:

• cerebrovascular disease,
• mental retardation and psychiatric illness,
• pulmonary infection, history of advanced COPD or respiratory failure,
• EF less than 40%, presence of cardiovascular disease,

This prospective randomized controlled double-blind study included a total of 80 ASA I-III patients aged 65-85 years undergoing cataract surgery under general anesthesia. Randomization Patients were randomly divided into two groups with frailty score as non-frail (40 patients) and pre-frail/frail (40 patients) by closed envelope method.
