Factors Predicting Slow Visual Recovery Following Hyperopic LASIK

Area of Science:

• Ophthalmology
• Refractive Surgery
• Corneal Surgery

Background:

• Hyperopic laser in situ keratomileusis (LASIK) is a common procedure for correcting farsightedness.
• Understanding factors influencing visual recovery is crucial for patient counseling and managing expectations.
• Previous studies have explored predictors of visual outcomes, but specific factors for slow recovery in hyperopic LASIK require further investigation.

Purpose of the Study:

• To identify predictive factors associated with delayed visual recovery following hyperopic LASIK surgery.
• To analyze baseline and intraoperative parameters that may correlate with a slower return to optimal visual acuity.

Main Methods:

• A retrospective analysis of 861 eyes from 861 patients who underwent hyperopic LASIK between January 2005 and December 2019.
• Patients were categorized into normal and slow visual recovery groups based on visual acuity at 1-week and 1-month follow-up visits.
• Binary logistic regression was employed to determine significant predictors of slow visual recovery, using an efficacy index of 0.9 or greater as the definition of recovery.

Main Results:

• A significant proportion of patients (28.9%) experienced slow visual recovery.
• Younger age, greater preoperative spherical equivalence, and increased maximum ablation depth were initially identified as predictors.
• Binary logistic regression confirmed female gender and greater preoperative spherical equivalence as significant independent predictors of slow visual recovery.

Conclusions:

• Female gender and higher degrees of preoperative hyperopic spherical equivalence are associated with a slower visual recovery after hyperopic LASIK.
• These findings can aid in patient selection and preoperative counseling, allowing for informed decision-making regarding refractive surgery.
• Further research may explore specific management strategies for patients identified with these risk factors.
