ABSTRACT
PURPOSE: To evaluate long-term efficacy, safety, and spectacle independence after the treatment of hyperopic presbyopia with pseudophakic mini-monovision using standard monofocal intraocular lenses (IOLs) after bilateral cataract surgery. SETTING: Private practice in Barcelona, Spain. DESIGN: Retrospective, noncomparative case series. METHODS: Patients with hyperopic presbyopia underwent bilateral cataract surgery with pseudophakic mini-monovision using standard monofocal IOLs between 2008 and 2018. Main outcomes analyzed were uncorrected distance visual acuity (UDVA), uncorrected near distance visual acuity (UNVA), and rates of spectacle independence at postoperative day 1 (POD1), months 1, 6 and 12, and at 5 and 10 years (Y10) postoperatively. RESULTS: The study enrolled 463 patients. Both UDVA and UNVA significantly improved postoperatively ( P < .05). The mean binocular UDVA improved from 0.47 ± 0.3 logMAR preoperatively to 0.096 ± 0.14 at POD1 to 0.16 ± 0.2 at Y10 ( P = .0033). The binocular UNVA was 0.05 logMAR at Y10, whereas in preoperative visits, all patients needed spectacles. The mean UDVA for the dominant eye ≤0.20 logMAR was achieved in 84.29% at the Y10. Self-reported and measured complete spectacle independence for near vision was achieved in 79.61% of patients at POD1 and 71.92% at Y10 postoperatively. For distance, respectively, in 86.29% of patients at POD1 and 78.43% at Y10. The achieved results were stable. No serious events were reported, as well as no photic phenomena. CONCLUSIONS: Pseudophakic mini-monovision in hyperopic presbyopes is a safe, effective, and low-cost approach for the long-term correction of presbyopia. It significantly reduces spectacle dependence and fulfils patients' expectations after bilateral cataract surgery.

OBJECTIVE: The objective of this article is to report two cases of black occlusive intraocular lens and implantation for treating intractable diplopia. CASE DESCRIPTIONS: Two patients with intractable diplopia after orbitofacial, trauma, and surgical removal of pituitary adenoma failed to conservative management. After uneventful cataract, phacoemulsification, a black intraocular lens was implanted in every case. In both cases, a complete degree of satisfaction was achieved, with no symptoms of diplopia, and no complications have been observed in their follow-up. The use of optical coherence tomography has been possible in both cases to assess the macula and optic nerve, since a fundoscopy is not possible in such cases. CONCLUSION: Implantation of a near-infrared transmitting occlusive intraocular lens for treating intractable diplopia provided a complete resolution of symptoms without eliminating the possibility of examining macula and optic nerve using optical coherence tomography.
