Hypothesis
The study aims to evaluate the long-term efficacy, safety, and predictability of ICL-V4c implantation for high and super-high myopic patients.
Conclusion
ICL-V4c implantation is effective, safe, and stable for correcting high and super-high myopia, but there is a potential for greater myopia regression in super-high myopic patients.
Supporting Evidence
- The efficacy index for high myopia was 0.91 after 5 years.
- The efficacy index for super-high myopia was 0.80 after 5 years.
- 11.67% of high myopia eyes were within ±0.50D at 5 years.
- The average axial length increased significantly more in super-high myopia patients.
Takeaway
Doctors used a special lens to help people see better without glasses, and it worked well for most patients, but some still had problems.
Methodology
The study reviewed 125 eyes from 64 patients who underwent ICL-V4c implantation and followed them for 5 years, measuring various visual and ocular parameters.
Potential Biases
Potential biases may arise from the retrospective design and the single-center nature of the study.
Limitations
The study is retrospective, has a limited sample size, and was conducted at a single center.
Participant Demographics
Patients aged 18-45 years with high and super-high myopia, with a mean age of approximately 32 years.
Statistical Information
P-Value
p=0.001 for axial length increase in super-high myopia
