“…Another potential reason is a decrease in IOP following cataract surgery. After phacoemulsification, a decrease in IOP can lead to an increase in ocular perfusion pressure, and as a result, CT and CVI increase [14,25,26]. In our study, IOP values were significantly decreased in both groups after surgery.…”

To evaluate the changes in choroidal vascular structures in patients with dry age-related macular degeneration (AMD) and healthy controls (No-AMD) after phacoemulsification. Methods: This prospective study was conducted in 34 eyes of 19 patients in the AMD group and 32 eyes of 20 patients in the no-AMD group who had uneventful phacoemulsification. Best-corrected visual acuity, slitlamp biomicroscopy, and intraocular pressure were recorded. Choroidal thickness (CT) measurements of the subjects were obtained using enhanced depth imaging optical coherence tomography (Edi-OCT) (RS-3000 Advance, Nidek, Japan), and choroidal vascular index (CVI) was calculated by using the binarization method at baseline and postoperatively at months 1 (M1) and 3 (M3) and the results were compared. Results: There was no significant difference between the patients in terms of age and gender (p=0.069, p=0.855 respectively). The mean CVI at baseline was 0.644 ± 0.019% in the AMD group and 0.657 ± 0.021% in the no-AMD group (p=0.025). In the AMD group, the CVI increased significantly in M3 compared to preoperative values (p=0.001). There was no significant difference between the two groups in terms of CT in baseline, M1, and M3 (p0.05). There was a significant increase in CT in M1 compared to preoperative values in both groups (p=0.026 and p=0.050, respectively). Conclusion: Although the preoperative CVI was lower in the AMD group than in the no-AMD group, there was a greater increase in CVI after phacoemulsification in the AMD group. While CT values return to normal after phacoemulsification sooner, CVI remains elevated for a longer period.

Phacoemulsification Induced Changes of Choroidal Thickness in Eyes with Age-Related Macular Degeneration

et al. 2020

Background and Objectives: Patients with cataract and age-related macular degeneration (AMD) may safely undergo cataract phacoemulsification to enhance visual acuity. Although it has not been proven that cataract surgery can cause AMD progression, different phacoemulsification effects are observed not only on retinal but also on choroidal tissues. The purpose of this study was to evaluate the effect of phacoemulsification on the choroidal thickness (CT) in eyes with and without AMD. Materials and Methods: In 32 eyes of 32 patients with senile cataract (No-AMD group) and in 32 eyes of 32 patients with cataract and dry AMD (AMD group), who had phacoemulsification without intraoperative complications and intraocular lens implantation, foveal retinal thickness (FRT) and CT were evaluated three times: at 1–2 post meridiem preoperatively, then 1 month and 3 months postoperatively, using 1050 nm swept source-optical coherence tomography (Topcon, Tokyo, Japan). Results: In both groups, a significant increase in FRT was observed after one month and a decrease after three months without reaching the baseline. One month after surgery, a sectorial CT increase was apparent in all sectors in both groups. A negative association between CT and age was disclosed in the No-AMD group almost for all regions at all time points. Furthermore, CT was significantly negatively associated with axial length (AL) in all sectors at all time points in the AMD group. Conclusion: Uneventful phacoemulsification may induce changes in the posterior eye segment. An increase in CT and FRT was observed in both groups one month after the surgery. However, three months after surgery, CT changes were different in both groups, while FRT decreased in both groups. CT changes negatively associated with age in the No-AMD group and with AL in the AMD eyes. These postoperative changes in the choroid and retina may not only lead to the late-onset pseudophakic cystoid macular edema but also to progression of AMD.
