This study examined the optical performance and safety of a newly designed multifocal intraocular lens (IOL) with five focal points (two additional "intensifiers") for cataract and presbyopia management. Conducted in Buenos Aires and Ramos Mejia, Argentina, the prospective, non-randomized observational study included 31 patients (61 eyes) who received bilateral implantation between March 2020 and November 2021. At the 3-month follow-up, all eyes achieved an uncorrected distance visual acuity (UCDVA) of at least 0.15 logMAR, with 93% achieving 0.1 logMAR and 44% achieving 0.0 logMAR. For intermediate vision at 80 cm, 98% of eyes achieved at least 0.1 logMAR, and 79% reached 0.0 logMAR. The results highlight the new multifocal IOL’s efficacy, particularly for intermediate and near vision, with high rates of spectacle independence and patient satisfaction.

This study aimed to assess the short-term refractive and visual outcomes following the implantation of the Hanita Intensity SL pentafocal intraocular lens (IOL) in patients with presbyopia. In a retrospective observational review, 20 eyes from 10 patients (70% female) who underwent immediate sequential bilateral surgery were evaluated over three months. Results showed that 100% of patients achieved visual acuity of 20/25 or better for both near and far distances, and 20/40 or better for intermediate distances. The defocus curve indicated excellent visual performance from infinity to approximately 33 cm, allowing functional vision at all distances. Additionally, all patients reported complete independence from glasses. These findings suggest that the Hanita Intensity SL IOL is a safe and effective option for achieving spectacle independence in presbyopic patients.

A clinical study comparing the new Intensity pentafocal IOL and a trifocal IOL showed that the Intensity IOL provides superior intermediate vision and a flatter defocus curve, with comparable distance and near vision. Patients reported fewer optical disturbances, such as glare and halos, with the Intensity IOL. Further research will clarify the specific benefits of the pentafocal design.

This study evaluated the AssiAnchor capsule device for stabilizing subluxated lenses in seven eyes of patients with Marfan syndrome or trauma. Results showed successful IOL implantation and significant improvements in visual acuity and refraction, with stable lens positioning during follow-up. The device proved effective with a manageable learning curve, offering a reliable solution for subluxated lens cases.
