Abstract

Introduction: Phacoemulsification with Intraocular Lens Insertion is a standard procedure that has been shown to enhance visual ability and quality of life for patients. Despite its high success rate, visual outcomes can differ across study populations.

Objective: The objective of this study is to identify the factors that contribute to the lack of improvement in visual outcomes among patients who have undergone Phacoemulsification and Monofocal Intraocular Lens Implantation procedures.

Method: This retrospective cohort study analyzed the medical records of 112 patients who underwent Phacoemulsification and Monofocal Intraocular Lens Implantation at Trat Hospital from 2021 to 2022. The study aimed to evaluate the difference in visual acuity (VA: logMAR) and visual function score (The Impact of Vision Impairment Questionnaire – Thai Version: Thai IVI) before and three months after the surgery. Multiple linear regression was employed to identify the factors affecting post-operative visual acuity and Thai IVI score. Multiple risk regression was then used to evaluate the factors associated with non-improvement outcomes.

Results: The average age of the sample group was 68.8 years, with 53.6% of the patients being female. 39.3% of the patients had ocular comorbidities, with glaucoma being present in 25 patients. 83% of all patients had moderate visual impairment (VA logMAR > 0.5). Following surgery, 97.3% of patients showed VA improvement, and 89.8% demonstrated Thai IVI score improvement. The complication rate was 8% (9 patients)

Post-operative complication, as well as ocular comorbidities, are significant independent variables that affect post-operative visual acuity (Final VA), resulting in a 15% higher chance of non-improvement of final VA (p.046). Final VA was also found to be a key factor affecting post-operative Thai IVI score (Final Thai IVI) (p.008). Patients with inferior final VA had a 43% increased chance of non-improvement in Final Thai IVI score (p<.001), while female patients had a 19% decreased chance of non-improvement in Final Thai IVI score (p.001).

Conclusion: Post-operative complication was a significant independent variable that could cause a lack of improvement in Final VA. A worsened final VA increased the likelihood of non-improvement in Final Thai IVI score. Additionally, female patients were found to have a decreased chance of non-improvement in Final Thai IVI score.
