“…A number of publications have reported the possible influence of cataract surgery on the choroid [ 2 , 3 , 9 , 10 ]. Aslan BS et al [ 9 ] have investigated the effects of uneventful phacoemulsification surgery on choroidal thickness using spectral domain optical coherence tomography (SD-OCT). They found that phacoemulsification may cause significant increase in choroid at all regions evaluated at 1 month postoperative follow-up.…”

BackgroundTo evaluate the changes of choroidal vascular structures in patients after phacoemulsification surgery.MethodsA self-control study was conducted on 36 eyes of 36 patients who had uneventful phacoemulsification. Choroidal images were acquired preoperatively, 7 days (D7), 1 month (M1), and 3 months (M3) after surgery from enhanced depth imaging (EDI) optical coherence tomography (OCT) scans. Choroidal vascularity index (CVI) was used to assess vascular status of the choroid using image binarization by the Niblack method. The postoperative values of mean CVI were compared with baseline by paired t-test. Univariate and multiple linear regression analyses were performed to determine the associations between CVI and other factors.ResultsThe mean age of the recruited patients was 63.1 ± 6.9 years. The mean CVI at baseline was 60.1 ± 5.5%. After surgery, the CVI significantly increased to 61.7 ± 5.3% at D7, 63.6 ± 4.4% at M1 and 64.8 ± 4.0% at M3 (p = 0.035, 0.0006, < 0.0001, respectively). Univariate and multiple regression analysis revealed a positive association between CVI and subfoveal choroidal thickness (SFCT) at pre-operation and no significant association with age, axial length (AL), intraocular pressure (IOP) and gender at all timepoints.ConclusionsPhacoemulsification induced increased CVI in patients diagnosed with cataract. Evaluation of the long-term change of CVI following surgery may provide valuable information for studying the relationship between phacoemulsification and disorders of the choroid.

“…There is scarce, inconclusive literature on this subject using enhanced-depth imaging with SD-OCT (Table 6). Some authors report a significant increase in choroidal thickness after surgery, 7,[15][16][17][18][19] whereas others report no significant change in choroidal thickness. 8,19 Noda et al noted that the changes in choroidal thickness persisted significantly even 6 months after surgery.…”

“…16 Potential causes may include ultrasound power used during surgery, intraoperative intraocular pressure fluctuations, and the intraoperative photostress from microscope light. 17,22 Participants were prescribed steroidal anti-inflammatory eye drops postoperatively. It is possible that choroidal thickness would have been more pronounced had anti-inflammatory drops not been given.…”

Background. Recent investigations show that phacoemulsification causing an inflammatory insult to the eye has an effect not only on retina but on the choroid as well. The purpose of this study was to evaluate the subfoveal choroidal thickness (SFCT) after uneventful phacoemulsification using swept-source optical coherence tomography (SS-OCT). Methods. This prospective study included 30 eyes of 23 patients with senile cataract undergoing uncomplicated phacoemulsification and intraocular lens implantation. SFCT and foveal retinal thickness (FRT) measurements were made at the same time, 1-2 PM preoperatively (P), 1 month (M1) and 3 months (M3) postoperatively using 1050 nm DRI Triton SS-OCT (Topcon, Tokyo, Japan). Postoperative changes in the SFCT, FRT and correlation of SFCT change with axial length, age, baseline intraocular pressure (IOP), IOP change were assessed. Results. The mean SFCT increased statistically significantly 3 months after surgery in all sectors except the superior inner region. Of the factors affecting the SFCT, the change in the SFCT (M3/P), correlation with age and baseline IOP in almost all sectors was observed. The mean FRT increased significantly after the surgery in all sectors. Conclusions. Insignificant subclinical increase in SFCT was observed 1 month after the cataract surgery. Significant increment in SFCT was detected 3 months postoperatively, which was correlated with surgery-induced IOP and ocular perfusion pressure change in the short term.
