Abstract Details


To compare the refractive and visual outcome after implantation of AT Lisa tri (Zeiss Meditec) multifocal intraocular lens (IOL) when applying LENSAR femtosecond laser for capsulotomy and crystalline lens fragmentation versus performing these steps manually by a single surgeon.


Optegra Yorkshire Eye hospital, Bradford, UK


Single surgeon (SR), single site. In a retrospective analysis the outcome of 21 consecutive patients who underwent IOL implantation after manual capsulorrhexis and standard phacoemulsification were compared to 21 consecutive patients who underwent IOL implantation using LENSAR for femtosecond laser assisted capsulotomy and crystalline lens fragmentation. The multifocal AT Lisa tri was implanted in all patients.


Patient demographics were similar between groups. Post-operative spherical equivalent in the LENSAR group was 0.43 ± 0.38 D and in the non-LENSAR group was -0.02 ± 0.50 D. Unaided distance visual acuity (UDVA) post-operatively was 0.07 ± 0.22 logMAR in the LENSAR group and 0.02 ± 0.14 logMAR in the non-LENSAR group. Post-operative CDVA was -0.03 ± 0.24 logMAR in the LENSAR group and -0.07 ± 0.08 logMAR in the non-LENSAR group. UNVA of N6 or better was achieved by 85% in the LENSAR group and by 90% in the non-LENSAR group. No complications occurred in either cohort.


Femtosecond laser-assisted refractive lensectomy with LENSAR produced similar outcomes for post-operative refraction, distance and near visual acuity compared to standard phaco lensectomy. The differences seen were neither clinically nor statistically significant.
