ABSTRACT
PURPOSE: To evaluate the safety and efficacy of a new multi-segmented refractive multifocal intraocular lens (IOL) after phacoemulsification and refractive lens exchange (RLE). PATIENTS AND METHODS: In this prospective, multicenter clinical trial, 63 presbyopic subjects who had cataract or where RLE candidates were bilaterally implanted with the Precizon Presbyopia IOL (Ophtec BV, Groningen, the Netherlands) after phacoemulsification. The study was conducted at 6 clinical centers in Germany, the Netherlands, Belgium, Turkey and Spain. Subjects were evaluated at baseline and at 1 day, 1 week, 1 and 3 months postoperatively for monocular and binocular uncorrected (UDVA) and corrected distance visual acuity (CDVA), uncorrected (UIVA) and distance-corrected intermediate visual acuity (DCIVA), uncorrected (UNVA), corrected (CNVA) and distance-corrected near visual acuity (DCNVA), contrast sensitivity and quality of vision. RESULTS: Three months postoperatively, binocular UDVA and CDVA of ≥20/40 was achieved in 98.4% (60/61) and 100%, respectively. Binocular UIVA and DCIVA of ≥20/40 was achieved in 96.7% (59/61) and 93.4% (57/61) respectively. Binocular UNVA, CNVA and DCNVA of ≥20/40 was achieved in 93.4% (57/61), 98.4% (60/61) and 95% (57/60) subjects, respectively. Complete spectacle independence was achieved in 80% (49/61) patients; 93% of patients reported that they were quite or very satisfied with the outcomes of the procedure. CONCLUSION: Precizon Presbyopia IOL implantation is a safe and effective method to provide good visual acuity at all distances in presbyopic and cataract patients.
ABSTRACT
ObjetivoConocer la viabilidad de la realización de la exploración oftalmológica básica de la patología ocular del paciente diabético desde el ámbito de la Atención Primaria de Salud (APS).DiseñoEstudio transversal observacional prospectivo y multicéntrico.Participantes y métodoMuestra de 712 diabéticos tipo II. Intervenciones: realización, por parte de un optometrista, de una exploración de la agudeza visual, medición de la presión intraocular y fotografía de fondo de ojo con cámara de retina no midriática. Interpretación de los resultados e indicación de derivación realizada, a doble ciego, por oftalmólogos y médicos APS.ResultadosAlteración agudeza visual: médico APS 43,7%, oftalmólogo 36,1%, concordancia 70%; sospecha glaucoma: médico APS 8,8%, oftalmólogo 7,6%, concordancia 94%; retinopatía diabética: médico APS 28,2%, oftalmólogo 13,4%, concordancia 78%. Derivación Servicios Oftalmología: médico APS 56,8%, oftalmólogo 41,3% (p=0,001).ConclusionesEl nivel de concordancia en los diagnósticos entre médico APS y oftalmólogo hace fiable la exploración oftalmológica del paciente diabético desde el ámbito de la APS. A pesar del supradiagnóstico y del 16% de derivación no justificada realizada por parte del médico APS, se evita la derivación a las consultas de oftalmología, de cerca de la mitad de los pacientes diabéticos(AU)

OBJECTIVE: To study the feasibility of a basic ophthalmological examination for the eye disease in diabetic patients by Primary Health Care (PHC). PATIENTS AND METHODS: A multi-centre prospective study. A sample of 712 type 2 diabetics. INTERVENTIONS: Visual acuity examination, intraocular pressure measurement and the eye fundus photograph with a non-mydriatic camera taken by an optometrist. The interpretation and subsequent referral to an ophthalmology department by ophthalmologists and general practitioners (GP). RESULTS: Visual acuity deficiency: GP, 43.7%; ophthalmologist, 36.1%; concordance, 70%; glaucoma suspicion: GP, 8.8%; ophthalmologist, 7.6%; concordance, 94%; diabetic retinopathy: GP, 28.2%; ophthalmologist, 13.4%; concordance, 78%. Ophthalmology Department referral: GP, 56.8%; ophthalmologist, 41.3% (P=0.001). CONCLUSIONS: Agreement between GP and ophthalmologist leads to a reliable ophthalmological examination of the diabetic patient in PHC. Despite an over-diagnosis and 16% of non-justified referrals by the GP, Ophthalmology Department referral is avoided in almost half of the diabetic patients.
