Purpose

To assess the relation between postoperative central macular tickness and contrast sensitivity in eyes after uncomplicated cataract surgery

Setting

Prospective, observational descriptive clinical study

Methods

We carried out a prospective, observational, descriptive clinical trial in patients undergoing cataract surgery with implant of enhanced monofocal intraocular lens (IOL). The inclusion criteria were as follows: patients scheduled for cataract surgery using ultrasound phacoemulsification and implant of enhanced monocular IOL, with no recognized central macular edema (CME) risks (diabetic retinopathy, retinal vascular disease, macular abnormality) and without surgical complications. The exclusion criteria included: previous ocular pathology, and surgical complications. In all cases optical coherence tomography (OCT) with macular cube 512x128 scan showing central macular thickness was performed preoperatively, and following cataract surgery at 24 hours, at 7 days and  at 30 days, identifying eyes with central macular thickening greater than 10 microns At the same time contrast sensitivity was assessed during the follow-up controls. Only one eye per patient was included in the study.

Results

A total of 102 patients were included in the clinical study. The mean macular thickness was 255 microns in the preoperative control, 258 microns at 24 hours and 7 days and 260 microns at 1 month in the postoperative period. Following the uncomplicated cataract surgery39 eyes showed central macular thickness value greater than 10 microns in relation with the previous values.  The statistical significance was p=0,00 with a confidence interval of 95%.  Eyes with central macular thickening ≤ 10 microns (measured using OCT) showed greater contrast sensitivity than those with thickening ≥ 10 microns at all spatial frequencies (p<0,012).

Conclusion

There is a significant number of eyes with increases in central macular thickness greater than 10 microns after uncomplicated cataract surgery. Increased in macular thickness ≥ 10 microns correlates with lower contrast sensitivity. These results suggest the limited efficacy of current prophylactic corticosteroid treatment. This reduction in contrast sensitivity following uncomplicated cataract surgery could explain the unsatisfactory patient-reported quality of vision in some cases after premium surgery.
