A preliminary study on the visual outcomes after LaserACE for presbyopia.

Area of Science:

• Ophthalmology
• Refractive Surgery
• Vision Science

Background:

• Presbyopia affects near vision, necessitating reading correction.
• Laser anterior ciliary excision (LaserACE) is a novel surgical approach for presbyopia.
• Investigating the long-term visual outcomes of LaserACE is crucial for its clinical adoption.

Purpose of the Study:

• To evaluate the visual outcomes of the LaserACE procedure in presbyopic subjects over a 12-month period.
• To assess the safety and efficacy of LaserACE for correcting presbyopia.
• To determine the impact of LaserACE on distance, intermediate, and near visual acuity.

Main Methods:

• A prospective, non-randomized study involving eight eyes of four presbyopic patients.
• LaserACE was performed using an erbium-YAG laser.
• Visual acuity, refraction, pupil size, and reading prescription were measured preoperatively and up to 12 months postoperatively.

Main Results:

• Significant improvements were observed in binocular distance-corrected intermediate visual acuity (DCIVA) and near visual acuity (DCNVA) at 6 and 12 months.
• A stable reduction in reading prescription by an average of 0.91 D at 40 cm was achieved.
• No significant changes were noted in manifest refraction, uncorrected distance visual acuity (UDVA), or corneal curvature.

Conclusions:

• LaserACE is a safe and effective procedure for presbyopia correction.
• The procedure enhances intermediate and near vision without compromising distance visual acuity or quality.
• Further research is needed to fully understand the mechanism and long-term effects of LaserACE.
