Abstract

Purpose

To evaluate the etiology and the clinical outcomes of secondary surgical interventions for dissatisfied patients after pseudophakic monovision.

Setting

Department of Ophthalmology, Kitasato University Hospital, Kanagawa, Japan.

Design

Retrospective case series.

Methods

This study comprised 12 eyes in 12 patients (age 66.2 ± 5.6 years) who underwent photorefractive keratectomy (PRK) enhancement to improve their dissatisfaction after pseudophakic monovision. We quantitatively assessed the visual and refractive outcomes and the subjective satisfaction measured using a visual analog scale, that ranged from 0 (very dissatisfied) to 10 (very satisfied), before and 3 months after PRK enhancement.

Results

Six (50%) of the 12 patients were dissatisfied with their various distance visions because of a large amount of anisometropia (≥2.50 D). Two (16.7%) were dissatisfied with their distance vision after conventional monovision because of residual cylindrical errors (≥0.75 D) in the dominant eye. Three (25%) was an unknown origin. The remaining one of the 12 patients was dissatisfied due to the unadaptability to crossed monovision. Eleven (91.7%) eyes were within ±0.5 D of the targeted correction after PRK enhancement. The overall satisfaction score was significantly improved, from 3.7 ± 2.4 (range 0–7) preoperatively to 6.0 ± 2.4 (range 2–9) postoperatively (p = 0.02). No vision-threatening complications were seen throughout the observation period.

Conclusions

PRK enhancement was effective with predictable refractive results and thus improved patient satisfaction for dissatisfied patients after pseudophakic monovision. These findings also suggest that the accurate correction of refractive errors plays a key role in successful pseudophakic monovision.
