Purpose
To evaluate changes in choroidal thickness before and after cataract surgery using enhanced depth imaging optical coherence tomography.
Setting
Prospective study
Methods
A prospective study was undertaken involving 40 eyes of 40 patients who underwent phacoemulsification. Subfoveal choroidal thickness was assessed preoperatively, at 7 days (D7), 1 month (M1), and 3 months (M3) postoperatively using the EDI-OCT technique. Additionally, central retinal thickness was measured concurrently. Stepwise analysis determined which factors (ie, age, CDVA, AL) were associated with changes in choroidal thickness.
Results
Analysis included 13 male participants (32,5%) and 27 female participants (67,5%), with a mean age of 64.73 years ± 10.34 (SD). The mean choroidal thickness was 215 ± 54.96 µm, which significantly increased to 245.42 ± 60.71 µm at D7, followed by a decrease to 232.58 ± 55.19 µm at M1, and further decreased to 219.13 ± 41 µm at M3. As for retinal thickness, the mean was 247.49 ± 4.12 µm, which significantly increased to 281.19 ± 5.20 µm at D7, then decreased to 262.50 ± 4.10 µm at M1, and finally to 251.92 ± 4.89 µm at M3. The changes in choroidal thickness correlated with the axial length.
Conclusions
Cataract surgery caused changes in choroidal thickness with a notable increase in mean SFCT postoperatively. However, these changes in SFCT reverted close to baseline levels after a span of 3 months. The axial length is critical for evaluating the changes in choroidal thickness.
