Under-correction or full correction of myopia? A meta-analysis.

Area of Science:

• Ophthalmology
• Optometry
• Vision Science

Background:

• Myopia progression is a significant concern in visual health.
• Understanding the impact of refractive correction strategies is crucial for management.

Purpose of the Study:

• To compare the efficacy of full versus under-correction in managing myopia progression.

Main Methods:

• A comprehensive meta-analysis of six studies (two RCTs, four non-RCTs) involving 695 participants.
• Inclusion of studies from major scientific databases.
• Statistical analysis using Comprehensive Meta-Analysis software.

Main Results:

• Non-cycloplegic refraction indicated that full correction was associated with less myopia progression compared to under-correction (p=0.175).
• Cycloplegic refraction showed a trend towards less myopia progression with full correction, though not statistically significant (p=0.085).
• No significant difference in myopia progression was observed between full and under-correction groups in either refraction method.

Conclusions:

• Full correction using non-cycloplegic refraction may be beneficial in reducing myopia progression.
• Further investigation into cycloplegic refraction's role in myopia progression is warranted.
