Visual Outcome and Patient Satisfaction of Inferior Segmental Low Power Near Addition Intraocular Lenses (IOLs)
Keywords:
intraocular lens, inferior segmental low power near addition intraocular lensesAbstract
Purpose: To evaluate visual outcome and patient satisfaction following implantation of inferior segmental
low power near addition intraocular lenses (IOLs)
Setting: Department of Ophthalmology, Ramathibodi Hospital, Faculty of Medicine, Mahidol University.
Bangkok, Thailand.
Study design: Prospective longitudinal case series.
Methods: This prospective case series involved consecutive 123 eyes (87 patients) who underwent
phacoemulsification with implantation of inferior segmental low power near addition IOLs (LS313-MF15,
Oculentis GmbH, Berlin, Germany) at the Department of Ophthalmology, Ramathibodi Hospital. The adding
power is plus 1.5 diopters of intraocular lens is approximate plus 1.0 diopter of glasses. Visual outcome,
halo, glare, ocular optical quality, spectacle dependence and scores in a questionnaire were assessed at
least 3 months postoperatively.
Results: The study included 87 patients. Postoperative visual outcome of 85 patients (97.7%) was improved.
Satisfaction with near vision was 72.42% in the High and Good categories, 26.44% in the Moderate and
Minimal groups and 1.15% in the Dissatisfied group. Satisfaction with distance vision was 82.76% in the High
and Good categories, 14.94% in the Moderate and Minimal groups and 2.30% in the Dissatisfied category.
Satisfaction comparison between preoperative and postoperative vision of patients was found to be 87.36%
in the High and Good groups categories, 11.49% in the Moderate and Minimal groups and 1.15% in the
Dissatisfied group. Some patients (5.7%) need glasses for distance vision due to myopia and astigmatism
and 23% need reading glasses.More than 90% reported no or mild halos, glare, starbursts, or other photic
phenomena.
Conclusions:The inferior segmental low power near addition intraocular lenses (IOLs) restored distance,
intermediate and near vision after cataract surgery, with high levels of patient satisfaction and low levels
of disturbing photic phenomena.
