Presbyopia Correction

Reduced dependence on glasses is an increasingly common expectation among those who want to take advantage of new surgical opportunities, especially for patients who lead an active lifestyle. Currently, due to the increase in the duration of active life in people over 40, there is a need for effective correction of presbyopia. Multifocal intraocular lenses are increasingly used in the treatment of presbyopia. After implantation of multifocal intraocular lenses most patients have no need for spectacle or contact vision. However, complications can affect the patient’s quality of life and level of satisfaction. The most common complications of multifocal correction are blurred vision and the presence of optical phenomena (“halo” and “glare”), associated with residual ametropia, clouding of the posterior capsule, large pupil size, anomalies of the wave front, dry eye and lens decentration. The main reasons for this are the failure to attempt to neuroadapt a patient, the dislocation of the lens, the residual refractive error and the clouding of the lens. The review presents the main features of various models of multifocal intraocular lenses, their implantation techniques, associated complications and methods for their correction. The development of multifocal correction of presbyopia and ametropia seems to be a promising direction in ophthalmic surgery.

Purpose: To compare objective image quality at distant, intermediate, and near foci with the corresponding visual acuity (VA) in patients symmetrically implanted with 5 different diffractive multifocal intraocular lenses (IOLs) (ReSTOR SV25T0, Tecnis ZKB00, Tecnis ZLB00, AT LISA 809, and AT LISA Tri 839MP) and a monofocal lens (Tecnis ZA9003) 3 months after cataract intervention. Methods: Objective image quality, measured as the area under the modulation transfer function curve (AMTF), was tested in vitro in an eye model. In addition, corrected distance visual acuity and distance-corrected intermediate and near visual acuities (DCIVA and DCNVA) were assessed in a group of 79 patients, randomly implanted with one of the lenses. Results: Image quality and VA at the distant focus was good for all lens designs, but was similarly compromised at the intermediate focus, where the best DCIVA corresponded to the low add ZKB00. At the near focus, the monofocal lens and the distance dominant SV25T0 had the worst AMTF values, with the ZLB00 presenting the best DCNVA. The relationship between AMTF and VA was found not to be linear, with VA being similarly good for AMTF values over a certain threshold. Conclusions: Visual acuity of pseudophakic patients reflected the optical quality of the specific IOL design within a certain range of measurements, beyond which maximum VA is limited by other ocular, optical, and neuropsychophysical factors.

Purpose To compare the NEI-RQL-42 quality of life questionnaire and the Radner Vissum reading test outcomes after bilateral cataract surgery with implantation of Tecnis ZCB00 monofocal and Tecnis ZMB00 multifocal intraocular lens (IOL). Methods Forty-two eyes of 21 patients who had phacoemulsification were implanted with Tecnis ZCB00 IOL and 82 eyes of 41 patients were implanted with Tecnis ZMB00 IOL. They answered the NEI-RQL-42 questionnaire before cataract surgery and 3 months after it. The Radner Vissum test was performed 3 months after the surgery with optical correction for near vision in patients with monofocal IOL, but without it in patients with multifocal IOL. Results Regarding the NEI-RQL-42 test, the multifocal group obtained better results in items 2, 7, 8, 11, 13, 31, and 40, and in the following categories: near vision, dependence on correction, and suboptimal correction (p<0.05). The monofocal group only showed better results in item 17. As for the Radner Vissum test, the multifocal group obtained significantly better results in phrases 1, 3, 4, and 5, and in the number of incorrect syllables (p<0.05). Conclusions Patients with Tecnis ZMB00 multifocal IOL report a higher quality of life regarding the lack of need for optical correction for near vision in their daily activities, but halos in vision at night. Additionally, patients with multifocal IOL achieve similar or better reading quality at near vision and under photopic lighting conditions than patients with monofocal IOL with near vision optical correction.

The core target of multifocal IOLs implantation is to provide advanced visual quality at different distances without spectacle or contact lenses that can be valuable when monofocal IOLs are implanted. Patients with monofocal IOLs need spectacles or contact lenses for the near and intermediate distance's vision. Multifocal intraocular lenses due to the optical part construction provide spectacle independence for patients in the postoperative period. The aim of this review was to analyze the modern approach to the several aspects of multifocal intraocular correction: spectacle independence, dysphotopsia, patient satisfaction. Patients’ questionnaire after surgery provides the data for evaluation of the quality of life, vision satisfaction at all range of distances on different levels of illumination, and patient activities of daily living. During the long period, a photic phenomenon (dysphotopsia) had been discussed in the literature as the principal reason for decrease of patients satisfaction with the treatment and lens explantation. Recently, high grade of spectacle independence and low risk of photic phenomena after modern multifocal IOLs implantation determine high-level patient satisfaction after cataract surgery. Multifocal intraocular correction is the effective technology for restoring passive accommodation that the wide range of the clinical studies proved. This review analyzes 33 studies (32 clinical studies and 1 metaanalisis) published in international peer-reviewed targeted titles.
