Abstract Details


To determine the effect of phacoemulsification on macular volume and thickness - using spectral domain optical coherence tomography (SD-OCT) examinations in cases operated on with / without posterior central circular capsulorhexis (PCCC).


A prospective comparative study conducted in St Donat Hospital, Varpalota, Hungary


Fifty subjects operated on with phacoemulsification and posterior chamber lens implantation one eye without PCCC (Standard group; 48 eyes) and fellow eye with PCCC (PCCC group; 50 eyes). All operations were uneventful and within 7-12 minute timeframe. Nine ETDRS areas of the macula were examined by SD-OCT preoperatively, 1 day, 1 week, 6 weeks, 3 moths, 6 months, 1 year and 2 years postoperatively. Postoperation care included Nepafenac (NSAID) drops for 2 months. Phacoemulsification times were also recorded.


There were statistically significant differences in macular volumes between preoperative and postoperative measures. Until 3 months macular thickness mildly increased, then slow decrease was observed in both groups. In the paracentral macular area, the thickness of superior (p=0.014); temporal (p=0.001); and nasal (p=0.021) quadrants increased. Peripheral macular thickness increased significantly in the superior (p=0.05) and temporal macular areas (p=0.001). The macular thickness increased significantly after phacoemulsification (p=0.001) until month 3, then decreased significantly until year 2. There was not significant difference in any meaning among PCCC and Standard groups. No correlations found between phacoemulsification time and macular thickness change.


Macular thickness in the nasal, superior, and temporal quadrants increased postoperatively until month 3, then slow decrease was observed. The long term decrease of paramacular thickness might have been related to the physiological cell loss. There was no statistically significant difference among PCCC and Standard group in any meaning. Cystoid macular oedema did not develop in any case; presumably due to the NSAID prevention treatment.
