To evaluate efficacy of breastfeeding on post-PRK results

Twelve women (23 eyes) who underwent PRK in 3 years ago while they were still breastfeeding and continued it for a few months (breastfeeding group- N) and twelve women (23 eyes) who were matched by age, diopter and operation data (non breastfeeding group- NB) covered by the study. Post PRK results and complications were compared between the two groups. T test, Generalized estimating equation, Fisher’s exact and 2χ tests were used for comparison of data. P-value less than 0.05 was considered statistically significant.

The average breastfeeding period before and after surgery in B were 11,25±4,60, 8,25±4,50 months. Respectively, using mitomycin C: 58,3% and 75,0%, after: 0,96±0,09, 0,97±0,05, BCVA before and after surgery: 1,0 and the efficacy indices were 96,97 and 97,3. After surgery, respectively, in B and NB, mild dry eye were seen in 58,3% and 66,7% cases; SE: 0,35±0,60 and 0,28±0,60 D (p=0,157) D (p=0,82), vertical trefoil (µm): 0,019±0,101 and 0,089±0,127 (p=0,02); minimal corneal thickness (µm): 457,72±46,78 and 434,54±101,97 (p=0,25); the best anterior fit sphere (D): 42,05±1,104 and 40,87±0,986 (p=0,00); posterior (D): 53,06±1,932 and 51,90±1,738 (p=0,03); cylindrical equivalent in corneal topography (D): 0,91±0,414 and 0,88±0,434 (p=0,01). Ectasia, corneal haze and myopic regression were not seen.

This study was performed at the first time moreover, 3 years after PRK, the results were not shown adverse effects of breastfeeding but, to continue of the study with more cases is required.
