Belin/Ambrósio Enhanced Ectasia Display in cataract surgery and relation to final visual acuity

ABSTRACT Objective To analyze and describe the coefficients found on maximum Ambrósio Relational Thickness-Maximum (ART-Max) and Belin/Ambrósio Enhanced Ectasia Display total deviation (BAD-D) in eyes with normal corneal topography subjected to cataract surgery with premium intraocular lens implantation and correlated these data with final visual acuity. Methods ART-Max and BAD-D data from 103 eyes of patients subjected to implantation of diffractive bifocal intraocular lens, with normal corneal topography who achieved visual acuity of 20/20 or 20/25 without correction after cataract surgery were analyzed. The groups with normal and abnormal values were compared using the chi-square test. Results Thirty-two (31.1%) and 71 (68.9%) eyes presented normal and abnormal ART-Max values, respectively. The difference between these groups was significant (p=0.0002). Fifty-five (53.4%) and 48 (46.6%) eyes had normal and abnormal BAD-D, respectively, and intergroup difference was not significant (p=0.9576). Conclusion Among patients with normal corneal topography who underwent premium intraocular and had good final visual acuity of 20/20 or 20/25, suspicious or abnormal indices of ART-Max and BAD-D were frequent, providing evidence that it possibly should not be a contraindication.
