AcrySof cachet phakic intraocular lens in myopic patients: visual performance, wavefront error, and lens position

Area of Science:

• Ophthalmology
• Biomedical Engineering
• Optometry

Background:

• Phakic intraocular lenses (PIOLs) are used for refractive error correction.
• Angle-supported PIOLs offer an alternative for myopia correction.
• The AcrySof Cachet PIOL is an angle-supported lens designed for myopia correction.

Purpose of the Study:

• To evaluate visual and aberrometric outcomes of the AcrySof Cachet PIOL.
• To assess the position of the AcrySof Cachet PIOL in the eye.
• To determine the safety and efficacy of the AcrySof Cachet PIOL for correcting myopia in adults.

Main Methods:

• Prospective study of 36 eyes with moderate to high myopia.
• AcrySof Cachet PIOL implantation to minimize refractive error.
• Follow-up up to 1 year, including visual acuity, aberrometry, and lens position measurements.

Main Results:

• Significant reduction in refractive error from -14.90 D to -0.29 D.
• Excellent uncorrected and corrected distance visual acuity achieved.
• Maintained safe endothelium-PIOL and PIOL-crystalline distances.
• No significant changes in higher-order aberrations observed.

Conclusions:

• The AcrySof Cachet PIOL is effective for moderate to high myopia correction.
• Provides excellent visual performance without altering ocular wavefront error.
• Maintains adequate distance from ocular structures, ensuring safety.
