Purpose
The aim of the study was to measure macular thickness before and after uncomplicated ultrasound phacoemulsification cataract surgery (PHACO) using optical coherence tomography (OCT) and to analyse the possible correlation with intraoperative variables of phacoemulsification – cumulative dissipated energy ( CDE ) and estimated fluid used ( EFU).
Setting
Prospective cohort study
Methods
The study included 30 healthy patients of both gender who successively underwent PHACO. Exclusion criteria were previous eye surgery, uveitis, ocular trauma, diabetes with or without retinopathy, earlier macular oedema of any etiology during any life period, argon laser treatment within three months prior the surgery, choroidal diseases, inability to perform OCT. Every patient underwent OCT macular thickness measurement and best corrected visual acuity (BCVA) analyse on the day of the surgery, 7 and 30 days after the surgery. For every patient intraoperative phaco variables were measured and recorded – CDE and EFU. All surgeries were performed by one surgeon on Centurion Alcon device.
Results
The mean age of patients was 68 ± 12. Most of patients were males (63%) versus female (37%), with no statistically significant difference between gender (Fisher exact test, p-value =0.71). BCVA was statistically significantly improved after PHACO (Wilcoxonov test, p<0.001) with preoperative BCVA 0.25±0.1 and postoperative BCVA 1.0 (-0.1) (Wilcoxon test, p<0.001). PHACO did not have significant impact on intraocular pressure (IOP), median IOP was 16 mmHg on all controls (Friedman test, p=0.63). Macular thickness was statistically increased after PHACO (Friedman test, P < 0.001), where the biggest differenece was before (242.5±20µm) and one month after PHACO (254±13µm) (Wilcoxon test, P = 0.001). Mean CDE was 9.73 (IQR 8.89 – 17.48), and EFU 46 ccm (IQR 39-57 ccm). Spearman coefficient of correlation did not confirm any correlation between CDE and EFU during PHACO on macular thickness changes.
Conclusion
PHACO resulted in significant improvement in BCVA. Although results confirmed a significant difference in macular thickness one month after the surgery, this increase did not directly correlate with CDE and EFU and fortunatelly did not influence the postoperative BCVA. No cystoid macular edema was noticed in this study.The changes in macular thickness were probably due to some other undetected comorbidities, surgical trauma by itself and other yet to be determined factors.
