Phacoemulsification with implantation of a trifocal intraocular lens in eyes with asteroid hyalosis and synchysis scintillans.

PURPOSE: To compare the visual outcomes in both eyes of patients who undergo phacoemulsification and trifocal intraocular lens (IOL) implantation and have asteroid hyalosis (AH) or synchysis scintillans (SS) in only one eye. METHODS: A retrospective comparative case series was performed. We evaluated uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), predictability, safety, efficacy, and satisfaction after implantation of the same model of trifocal IOL in both eyes (PhysIOL FineVision Pod-F and Micro-F and Rayner RayOne Trifocal). RESULTS: A total of 164 eyes of 82 patients (41 females, 50%) met the inclusion criteria. There were no statistically significant differences in sphere, cylinder, spherical equivalent, UDVA, UIVA, or UNVA between the groups. Postoperative CDVA was slightly better in the control group (logMAR 0.03) than in the AH/SS group (logMAR 0.04) (P: 0.014). There were no statistically significant differences in predictability, safety index, or efficacy index between the groups. Overall subjective satisfaction was good (98.2%). CONCLUSIONS: Visual outcomes and satisfaction are good after implantation of trifocal IOLs in eyes with AH or SS. Therefore, trifocal IOLs should not be ruled out in these patients when no other vitreoretinal disorder is present.

Visual outcomes of combined use of implantable collamer lens implantation and laser corneal visual correction for myopia over -18.00 diopters.

PURPOSE: To explore visual outcomes in patients with extreme myopia receiving an implantable collamer lens (ICL) at -18.00 diopters (D), with central port, followed by bioptics by laser vision correction (laser in situ keratomileusis [LASIK] or photorefractive keratectomy [PRK]) to address residual myopia or myopic astigmatism. SETTING: Clínica Baviera (Aier Eye Hospital Group), Bilbao, Spain. DESIGN: Retrospective analysis of cases. METHODS: The study assessed uncorrected distance visual acuity, corrected distance visual acuity (CDVA), predictability, safety, efficacy, and patient satisfaction after implantation of the ICL and bioptics. The model implanted was V4c and EVO, with a correction of -18.00 D. Bioptics were performed at least 3 months after implantation, and patients were followed up for at least 3 months after LASIK or PRK. RESULTS: The analysis included 125 eyes from 90 patients. Of these, 51.2% underwent LASIK and 48.8% PRK. Mean time from implantation to bioptics was 5.9 ± 9.4 months. Patients were followed up for a mean of 40.2 ± 37.9 months after bioptics. Median manifest refractive spherical equivalent was -2.89 D before bioptics and -0.49 D after. Median CDVA was 0.18 logMAR before bioptics and 0.17 after. The mean safety and efficacy indices were 2.22 ± 1.88 and 2.06 ± 1.85, respectively. CONCLUSIONS: Visual outcomes and safety indices after ICL implantation and subsequent LASIK or PRK in patients with extreme myopia are excellent.

Visual Outcomes and Patient Satisfaction After Bilateral Refractive Lens Exchange With a Trifocal Intraocular Lens in 5,226 Patients With Presbyopia.

PURPOSE: To assess visual and refractive outcomes and visual function after bilateral RayOne Trifocal toric and nontoric intraocular lens (IOL) (Rayner) implantation in patients with presbyopia. METHODS: Charts of patients with presbyopia who underwent refractive lens exchange with bilateral implantation of the RayOne Trifocal IOL (toric and non-toric) were retrospectively reviewed. Visual and refractive outcomes were evaluated at 3 months. Patient satisfaction, spectacle independence, and visual disturbance profile were assessed by questionnaires. RESULTS: A total of 5,226 patients were assigned to one of two groups: 1,010 patients had toric IOL implantation (toric group) and 4,216 patients received the non-toric model (non-toric group). Mean ± standard deviation visual acuity at 3 months for the toric group was binocular uncorrected distance visual acuity (UDVA) of 0.07 ± 0.11 logMAR, monocular corrected distance visual acuity (CDVA) of 0.05 ± 0.07 logMAR, binocular uncorrected near visual acuity (UNVA) at 40 cm of 0.10 ± 0.09 logMAR, binocular uncorrected intermediate visual acuity (UIVA) at 40 cm of 0.13 ± 0.12 logMAR, postoperative spherical equivalent (SE) of -0.21 ± 0.47 diopters (D), and cylinder of -0.34 ± 0.40 D. The non-toric group had binocular UDVA of 0.04 ± 0.08 logMAR, monocular CDVA of 0.05 ± 0.07 logMAR, binocular UNVA of 0.10 ± 0.08 logMAR, binocular UIVA of 0.13 ± 0.11 logMAR, SE of -0.08 ± 0.38 D, and cylinder of -0.28 ± 0.34 D. No statistically significant differences were found in achieving spectacle independence and there were high levels of satisfaction in both groups. CONCLUSIONS: In this retrospective analysis with more than 5,000 patients, both the toric and non-toric RayOne Trifocal IOL models provided good visual performance at all distances, resulting in excellent levels of spectacle independence and patient satisfaction.

Incidencia de la queratitis infecciosa y resultados de 351 712 procedimientos de cirugía refractiva con láser excimer / Infectious keratitis incidence and outcomes for 351 712 laser-assisted in situ keratomileusis surgical procedures with excimer laser

Estudiar la incidencia de queratitis infecciosas (QI) tras la cirugía refractiva con láser excimer (laser assisted in situ keratomileusis [LASIK] y ablación de superficie [AS]: LASEK y PRK) el diagnóstico, la actitud terapéutica adoptada, el manejo y los resultados. Material y método: Hemos realizado un estudio retrospectivo multicéntrico en 351 712 ojos intervenidos consecutivamente, de todos aquellos casos susceptibles de ser diagnosticados como QI por la clínica o los hallazgos biológicos. Resultado: Se recolectó un total de 147 casos de QI (lo que supone una incidencia del 0.0417%) ; en 100 casos lo fueron tras la LASIK (0.0307%) y 47 tras la AS (0.176%). La infección corneal se presentó en el 57.8% en el ojo derecho y en el 42.2% en el ojo izquierdo; en 12 pacientes la presentación fue bilateral. El tiempo transcurrido desde la cirugía LASIK hasta el comienzo de los síntomas fue de 16 ± 32 días, fue temprano en el 62%; tras la AS, fue a los 13 ± 26 días (rango: 1 a 160), el 71.79% se presentó en la primera semana. En 23 casos, tras la LASIK, de los 74 en los que se tomaron muestras, el resultado del cultivo fue positivo. Se tomaron muestras en 33 casos de la serie de AS, 15 de los cuales fueron positivos. En el grupo de LASIK, el 22% de los ojos perdió una o más líneas de su agudeza visual lejana corregida (CDVA), mientras que en el 53% de los ojos la visión final fue de 20/20 y en el 95% lo fue de 20/40 o mejor. En 31 ojos (66%) del grupo de AS se mantiene la CDVA; la visión final fue de 20/20 en el 54.7% y de 20/40 en el 93.6% de los ojos. Conclusiones: La incidencia de infección después de la LASIK es baja, pero la tasa de infección después de la AS es estadísticamente más elevada. La aparición de esta complicación en pacientes asintomáticos subraya la necesidad de revisiones posoperatorias. No hemos encontrado diferencias estadísticamente significativas entre la agudeza visual final tras infecciones después de AS y de LASIK...
