Summary
The Artisan toric phakic intraocular lens (TPIOL) safely and effectively corrects high myopia or hyperopia with astigmatism. This study found predictable, stable results with high patient satisfaction after TPIOL implantation.
Area of Science:
- Ophthalmology
- Refractive Surgery
Background:
- High ametropia and astigmatism present significant challenges for vision correction.
- Toric phakic intraocular lenses (TPIOLs) offer a potential solution for correcting these refractive errors.
Purpose of the Study:
- To evaluate the safety, efficacy, predictability, stability, and patient satisfaction of the Artisan TPIOL for correcting myopia or hyperopia with astigmatism.
Main Methods:
- A prospective, nonrandomized, multicenter trial involving 70 eyes of 53 patients.
- Patients with high myopia or hyperopia with astigmatism underwent TPIOL implantation.
- Outcomes assessed included visual acuity, refraction, endothelial cell count, intraocular pressure, and patient satisfaction over a 6-month follow-up.
Main Results:
- No loss of best spectacle-corrected visual acuity (BSCVA) was observed; 46 eyes gained BSCVA.
- Uncorrected visual acuity (UCVA) was 20/40 or better in 88.6% of eyes.
- Refractive outcomes were highly predictable, with 72.9% within +/-0.50 D of target refraction. No serious complications occurred.
Conclusions:
- Artisan TPIOL implantation is a safe and effective procedure for correcting high ametropia and astigmatism in a single step.
- The refractive correction provided by the Artisan TPIOL is stable at 6 months post-surgery.
- High patient satisfaction was reported, indicating a favorable outcome for the procedure.
