OBJECTIVE: The aim of this study is to compare subfoveal choroidal thickness (SFCT) before and after uneventful phacoemulsification using enhanced depth imaging optical coherence tomography (EDI-OCT). BACKGROUND: Cataract is a major cause of visual impairment in the elderly. Cataract surgery is the most common ophthalmic surgery and is performed simultaneously with glaucoma or vitreous surgery in many cases. However, according to the results in epidemiology studies, cataract surgery is associated with the onset of age-related macular degeneration (AMD) and cataract surgery increases visual acuity in these patients without an increased risk of progression to exudative AMD. METHODS: A prospective study was conducted on 53 eyes of 53 patients who had phacoemulsification. Measurements of SFCT were performed preoperatively, 7 days (D7), 1 month (M1), and 3 months (M3) postoperative using the EDI-OCT technique. Central retinal thickness was also measured at the same time. RESULTS: Twenty-seven male (50.9%) and 26 female (49.1%) with a mean age of 56.43 years ± 10.34 (SD) were analyzed. The mean choroidal thickness was 199.9 ± 60.74 µm. It significantly increased to 228.42 ± 59.77 µm at D7, then decreased to 210.78 ± 59.59 µm at M1, and then decreased to 200.63 ± 61 µm at M3. The mean retinal thickness was 260.79 ± 6.12 µm. It significantly increased to 294.09 ± 7.20 µm at D7 and then decreased to 274.70 ± 6.00 µm at M1 and 258.92 ± 5.89 µm at M3. CONCLUSION: Mean SFCT increased after cataract surgery. The changes in SFCT return to near the baseline after 3 months.
