To compare biometry predictability, postoperative binocular distance and near unaided visual acuity and complications rate after femtosecond laser (FSL) assisted and standard phacoemulsification with a multifocal refractive IOL.

Prospective, non-randomized,  comparative, single-surgeon, case series conducted at Moorfields Eye Hospital, Private Patients Unit. The study included 56 patients (112 eyes) who underwent sequential bilateral FSL-assisted phacoemulsification (28 patients) or standard phacoemulsification (28 patients) with a single type of multifocal refractive IOL implantation. Biometry predictability, postoperative binocular unaided distance and near visual acuity and complications rate of the 2 groups (femto group and standard group) were recorded and analysed at final follow-up (1-3 months).

There were no demographic differences in the two groups. Biometry predictability was -0.11±0,45 D in the femto group and -0.15±0.42 D in the standard group (p=0.42). Postoperative binocular unaided distance visual acuity was -0.03±0.69 logMAR in the femto group and -0.03±0.73 logMAR in the standard group (p=0.99). Postoperative binocular near visual acuity was J2 or better in 76% of eyes in femto group and 73% of eyes in the standard group (p=0.99). No intraoperative complications occurred; one patient, belonging to the femto group, experienced Irvine-Gass syndrome that resolved completely in 4 weeks after topical treatment.

Both FSL-assisted phacoemulsification and standard phacoemulsification resulted in similar and comparable refractive and visual outcomes. No statistical significant difference was found in any of the parameters evaluated.
