Summary
The 6mm Artisan lens effectively corrects high myopia up to -16D, improving visual acuity in most patients. Long-term safety requires further investigation due to incomplete follow-up.
Area of Science:
- Ophthalmology
- Refractive Surgery
Background:
- High myopia presents significant visual challenges.
- Phakic intraocular lenses offer a surgical correction option.
Purpose of the Study:
- To evaluate the safety and efficacy of the 6mm Artisan iris claw phakic intraocular lens.
- To assess its use in correcting high myopia.
Main Methods:
- Twenty-five eyes with myopia ranging from -7.50D to -16D were implanted with the 6mm Artisan lens.
- A 24-month follow-up period was conducted.
Main Results:
- Mean preoperative spherical equivalent refraction was 13.08+/-3.44D, reducing to 0.77+/-0.57D postoperatively.
- 81.8% of eyes achieved a spherical equivalent refraction within +/-1.00D.
- Best spectacle-corrected visual acuity improved or was maintained in 62.5% of cases, with no observed iritis, cataract, or glaucoma.
Conclusions:
- The 6mm Artisan lens is effective for myopia reduction up to -16D.
- Predictable outcomes and visual acuity gains were observed.
- Long-term safety cannot be determined due to incomplete follow-up.
