Background: Recent development of cataract surgery has led to the improvement of visual outcomes. However, pseudophakic cystoid macular oedema (CME), which is also known as Irvine–Gass syndrome, remains a usual cause of unexpected visual disturbance after both complicated and uncomplicated cataract surgeries. Optical coherence tomography is an important method in detecting changes prior to clinical presentation.Aim: To assess macular thickness changes after uncomplicated phacoemulsification using spectral domain optical coherence tomography (SD-OCT).Setting: The study assessed healthy patients who had uneventful phacoemulsification and changes in macular thickness in Ibn Al Haitham Teaching Eye Hospital (tertiary eye center), Baghdad, Iraq.Methods: Macular thickness of 86 eyes with uncomplicated phacoemulsification were measured by using four OCT examinations: one preoperatively, which was used as a control, and three in the first week and first and second months. Incidence of macular thickness changes was evaluated in the central and para and perifoveal areas to detect which areas of the macular map will be affected more. Significance was tested by using paired t-test and p 0.05 was considered significant.Results: Significant increase in macular thickness postoperatively during the 2-month period reaching the maximum level in the second month; early significant changes were noticed in paracentral area in the first week whilst significant increase in the central and pericentral area was recorded in the first month. Cystoid macular oedema (CME) was detected in six eyes (7%) in the second month.Conclusion: Significant variation in macular thickness can occur after uneventful phacoemulsification surgery in healthy patients. Cystoid macular oedema was detected in 7% of our patients using SD-OCT. It is rare after uncomplicated phacoemulsification in healthy individuals but should be kept in mind in the follow-up period. A detailed fundus examination with OCT imaging is thus recommended in the first or second month postoperatively for the early detection and treatment of CME.

“…In phacoemulsification, the mechanical effects resulted from ultrasound energy and liquid regulation in that surgery due to compression reaction and hypoxia in the tissue. 15 One week after phacoemulsification, the thickness of peripapillary RNFL increased in every quadrant (superior, inferior, temporal, and nasal) and in the mean of all quadrants, even though the differences were not statistically significant. The increase of peripapillary RNFL thickness was greater in glaucoma group compared to non-glaucoma.…”

Changes in peripapillary retinal nerve fiber layer thickness in chronic glaucoma and non-glaucoma patients after phacoemulsification cataract surgery

et al. 2015

ABSTRAK ABSTRACTBackground: Phacoemulsification is a common cataract operation nowadays. During phacoemulsification, variation in intraocular pressure (IOP) may occur, which might change the retinal nerve fiber layer (RNFL) thickness. This study was aimed to evaluate the change in peripapillary RNFL thickness and mean deviation (MD) of visual field after phacoemulsification in chronic primary glaucoma and nonglaucoma patients.

“…In the present study, an approximately 20 μ m mean increase in CFT was significantly noted at 1 month after cataract surgery. A previous study has shown an increase in retinal thickness of approximately 21.7 μ m after cataract surgery in healthy eyes [ 25 ]. Thus, a 20 μ m increase in CFT in our patient may not be an unusual finding.…”

et al. 2021

Purpose. This study aimed to evaluate the short-term outcomes of cataract surgery in patients with a history of idiopathic central serous chorioretinopathy (CSC). Methods. This retrospective study included 26 patients with a history of CSC who underwent uncomplicated phacoemulsification and intraocular lens implantation. The best-corrected visual acuity (BCVA) and central foveal thickness (CFT) measured before the surgery were compared with those obtained at mean 3.6 months after the surgery. BCVA outcome was also analyzed in eyes with and without subretinal fluid (SRF). Results. The mean logarithm of the minimal angle of resolution BCVA significantly improved from 0.52 ± 0.40 before the surgery to 0.21 ± 0.30 one month after the surgery and 0.20 ± 0.31 at 3.6 months after the surgery ( P < 0.001 ). The mean CFT was 281.2 ± 84.2 μm before the surgery, 301.5 ± 90.7 μm one month after the surgery, and 279.9 ± 83.6 μm at 3.6 months after the surgery. The CFT before surgery was not different from those measured at 3 months ( P = 0.253 ). Significant improvement in BCVA at 3.6 months was noted in the SRF group (N = 12, P = 0.003 ) and the non-SRF group (N = 14, P = 0.001 ). CSC recurrence was noted in 2 patients in the non-SRF group. Conclusions. Significant improvement in visual acuity was noted after cataract surgery in patients with a history of idiopathic CSC, without a risk of aggravation of CSC in most patients.
