Abstract Details


To compare the refractive and visual outcome after implantation of the AT Lisa tri (Zeiss Meditec) multifocal intraocular lens (IOL) when applying different surgical approaches: standard phacoemulsification, LENSAR femtosecond laser for capsulotomy and crystalline lens fragmentation and LENSAR femtosecond laser in conjunction with the implantation of a capsular tension ring (CTR).


Optegra Eye Hospital Yorkshire, Bradford, UK


Single surgeon (SR), single site. In a retrospective analysis the outcome of 62 patients who underwent IOL implantation after manual capsulorrhexis and standard phacoemulsification were compared to 29 patients who underwent IOL implantation using LENSAR for femtosecond laser assisted capsulotomy and crystalline lens fragmentation and to 56 patients who underwent the LENSAR procedure and in addition a CTR was implanted. The multifocal AT Lisa tri was implanted in all patients. Data of right eyes was analysed only and visual acuity was measured on a logMAR scale. Patient demographics were similar between groups. No operative complications occurred.


Spherical equivalent in the standard group was 0.02±0.40 D, in the LENSAR group 0.06±0.40 D and in the LENSAR&CTR group -0.03±0.27 D. In the standard and LENSAR group 86% of eyes were with ±0.50D of the predicted refraction, respectively, and in the LENSAR&CTR group it was 100%. UDVA was 0.02±0.13 in the standard group, -0.02±0.08 in the LENSAR group and -0.03±0.08 in the LENSAR&CTR group. CDVA was -0.07±0.06 in the standard group, -0.08±0.06 in the LENSAR group and -0.05±0.07 in the LENSAR&CTR group. UNVA of N6 or better was achieved by 81%, 84% and 83% in the standard, LENSAR and LENSAR&CTR group, respectively.


Femtosecond laser-assisted refractive lensectomy with LENSAR and CTR produced slightly better results for post-operative refraction. Distance and near visual acuity was similar in all groups. The differences seen were neither clinically nor statistically significant.
