Visual and satisfaction results with implantation of the trifocal Panoptix (R) intraocular lens in cataract surgery

Purpose: To assess visual results (including the Lapid-Kushlin defocus coefficient), and satisfaction, following the implantation of PanOptix® a trifocal intraocular lens.Methods: Observational, retrospective cohort study. 130 eyes of 65 subjects with bilateral implantation were included. Binocular uncorrected visual acuities [distance (Binocular UDVA), intermediate (Binocular UIVA) and near (Binocular UNVA)] were measured. Also, the manifest refraction, binocular defocus curve and binocular contrast sensitivity were determined. The Lapid-Kushlin defocus coefficient, a new single numerical parameter based on the area under the curve of the defocus curve, was calculated. The validated Spanish CATQUEST-9SF satisfaction survey was applied.Results: Postoperative visual acuity ranges were: binocular UDVA 0.18 to 0.0 LogMAR, binocular UIVA 0.30 to 0.0 LogMAR and Binocular UNVA 0.18 to 0.0 LogMAR. The levels of contrast sensitivity both in bright light conditions (with and without glare) and low light conditions with glare, remained within the limits of normality. Under scotopic conditions without glare values below normality were found at lower spatial frequencies. The binocular defocus curve showed a plateau without a clearly evident peak. The Lapid-Kushlin defocus coefficient was 0.199. Two patients (3.1%) needed glasses after the procedure for near and intermediate vision. No patient manifested great visual difficulties or was dissatisfied with the results.Conclusions: The trifocal platform showed very good results in this series of patients. 96.9% of the patients achieved independence of the glasses and expressed a high degree of satisfaction. The Lapid-Kushlin defocus coefficient was better than those calculated from literature, for other multifocal intraocular lenses. (AU)

Figura A. OI: fotografía en lámpara de hendidura con filtro de azul de cobalto. La tinción con fluoresceína permite apreciar dos úlceras separadas de aspecto dendrítico (flechas blancas) que comprometen la media periferia, tanto superonasal (meridiano de las 9 y 10:30 horas), como superior (meridiano de las 12 y las 2 horas). Adicionalmente, lesión ulcerativa con compromiso estromal de aproximadamente de 3x2 mm con adelgazamiento de más del 50 % del espesor corneal (óvalo blanco). Figura B. OI: tomografía de coherencia óptica de la córnea. Se observa área de adelgazamiento (remanente estromal respetado de 171 µm) con quiste epitelial sobre el área de ulceración estromal. Figura C. OI: fotografía en lámpara de hendidura con filtro de azul de cobalto. La tinción de fluoresceína permite apreciar solo mínima captación del colorante sobre las áreas de las úlceras dendríticas epiteliales, así como cicatrización casi completa de la ulceración estromal. Figura D. OI: tomografía de coherencia óptica de la córnea. Epitelización completa del área adelgazada (que alcanza ahora 276 µm de espesor) con desaparición casi total del quiste epitelial.

Figure A. OS: Slit-lamp biomicroscopy photograph with Cobalt Blue Filter. Fluorescein staining reveals two separate dendritic ulcers (white arrows) compromising the mid-periphery, both superonasal (at 9 and 10:30 o'clock), and superior (at 12 and 2 o'clock). Additionally, an ulcerative lesion with stromal compromise of about 3x2 mm with thinning of more than 50% of the total corneal thickness (white oval). Figure B. OS: optical coherence tomography of the cornea. An area of thinning (respected stromal remnant of 171 µm) with epithelial cyst on the stromal ulceration area. Figure C. OS: Slit-lamp biomicroscopy photograph with Cobalt Blue Filter. Fluorescein stain shows minimal staining on areas of epithelial dendritic ulcers, as well as almost complete healing of the stromal ulceration. Figure D. OS: optical coherence tomography of the cornea. Complete epithelialization of the thinned area (now reached thickness of 276 µm) and almost complete resolution of the epithelial cyst.
