PRIMARY outcome

Timeframe: Up to 3 years

Population: The data are expressed as mean±standard error. Comparisons before and after treatment of the BCVA were analyzed using the paired t-test.A probability (P) value of less than 0.05 was considered statistically significant.Lower logMAR represents a better outcome.
