Item Agreement between central corneal thickness measured using pentacam, ultrasound pachymetry, specular microscopy and optic biometer lenstar LS 900 and the influence of intraocular pressure(Ophthalmologica, 2014) Borrego Sanz, Lara; Saenz Frances, Federico; Bermudez Vallecilla, M. C.; Morales Fernández, Laura; Martínez De La Casa Fernández-Borrella, José María; Santos Bueso, Enrique; Jañez Escalada, Luis; García Feijoo, JuliánPurpose: To compare central corneal thickness (CCT) values obtained by Lenstar (LE), Pentacam (PC), specular microscopy (SM) and ultrasound pachymetry (UP) in healthy corneas and study their influence on intraocular pressure (IOP) readings determined by Goldmann applanation tonometry (GAT). Methods: CCT was measured in 76 healthy subjects by LE, PC, SM and UP. We established Lin's concordance correlation coefficient (ρ-C) between different techniques. The influence of CCT on GAT was established through univariate linear regression models, IOP being the dependent variable. Results: The highest ρ-C was found between LE and SM at 0.94 (95% CI: 0.91-0.96) and between LE and UP at 0.95 (95% CI: 0.94-0.97). IOP readings showed less variability when CCT was determined using LE (7.7%, B = 0.16; 95% CI: 0.004-0.28). Conclusions: Although CCT values obtained with UP, PC, SM and LE show good correlation, these methods are not completely interchangeable. The amount of IOP variation differs when CCT is determined using LE or SM.Item Visual outcomes after bilateral trifocal diffractive intraocular lens implantation(BMC Ophthalmology, 2015) Carballo Álvarez, Jesús; Vázquez Molini, José María; Sanz Fernández, Juan Carlos; García Bella, Javier; Polo Llorens, Vicente; García Feijoo, Julián; Martínez De La Casa Fernández-Borrella, José MaríaBackground In recent years new models of intraocular lenses are appearing on the market to reduce requirements for additional optical correction. The purpose of this study is to assess visual outcomes following bilateral cataract surgery and the implant of a FineVision® trifocal intraocular lens (IOL). Methods Prospective, nonrandomized, observational study. Vision was assessed in 44 eyes of 22 patients (mean age 68.4 ± 5.5 years) before and 3 months after surgery. Aberrations were determined using the Topcon KR-1 W wave-front analyzer. LogMAR visual acuity was measured at distance (corrected distance visual acuity, CDVA 4 m), intermediate (distance corrected intermediate visual acuity, DCIVA 60 cm) and near (distance corrected near visual acuity, DCNVA 40 cm). The Pelli-Robson letter chart and the CSV-1000 test were used to estimate contrast sensitivity (CS). Defocus curve testing was performed in photopic and mesopic conditions. Adverse photic phenomena were assessed using the Halo v1.0 program. Results Mean aberration values for a mesopic pupil diameter were: total HOA RMS: 0.41 ± 0.30 μm, coma: 0.32 ± 0.22 μm and spherical aberration: 0.21 ± 0.20 μm. Binocular logMAR measurements were: CDVA −0.05 ± 0.05, DCIVA 0.15 ± 0.10, and DCNVA 0.06 ± 0.10. Mean Pelli-Robson CS was 1.40 ± 0.14 log units. Mean CSV100 CS for the 4 frequencies examined (A: 3 cycles/degree (cpd), B: 6 cpd, C: 12 cpd, D: 18 cpd) were 1.64 ± 0.14, 1.77 ± 0.18, 1.44 ± 0.24 and 0.98 ± 0.24 log units, respectively. Significant differences were observed in defocus curves for photopic and mesopic conditions (p < 0.0001). A mean disturbance index of 0.28 ± 0.22 was obtained. Conclusions Bilateral FineVision IOL implant achieved a full range of adequate vision, satisfactory contrast sensitivity, and a lack of significant adverse photic phenomena.

Design Prospective interventional case series. Methods In 50 eyes of 25 myopic subjects consecutively scheduled for ICL implant, FDOCT (RTVue; Optovue Inc) iridocorneal angle measurements were made before and 1 and 3 months after surgery. Trabecular-iris angle (TIA) and angle opening distance 500 μm anterior to the scleral spur (AOD500) were compared among the quadrants nasal, temporal, and inferior, and correlations with ocular variables including lens vault were examined. Results Preoperative TIA was 48.7 ± 8.7, 48.2 ± 8.7, and 48.7 ± 9.3 degrees for the nasal, temporal, and inferior quadrants, with no differences (P= 1.000). Following ICL implant, corresponding values fell to 31.2 ± 11.5, 30.0 ± 10.7, and 29.7 ± 8.1 degrees at 1 month postsurgery, indicating angle narrowing of 34%-42%, and to 30.6 ± 12.3, 30.1 ± 11.9, and 29.8 ± 12.3 degrees, respectively, at 3 months postsurgery. Angle measurements failed to vary between 1 month and 3 months postsurgery (P= .481). In 8 eyes, iridotrabecular contact attributable to surgery was observed. One month after surgery, vault measurements correlated with TIA (R = -.309;P= .048). Six variables were identified as predictors of TIA at 1 month postsurgery (R2= .907). Conclusions Although considerable angle narrowing was detected 1 month after ICL V4c implant, this narrowing remained stable at 3 months postsurgery. Factors predictive of TIA could serve to identify suitable candidates for ICL placement.Item Computational Study of Aqueous Humor Dynamics Assessing the Vault and the Pupil Diameter in Two Posterior-Chamber Phakic Lenses(Investigative Ophthalmology & Visual Science, 2016) Fernández Vigo, José Ignacio; Macarro Merino, Ana; Fernández Francos, Joaquín; De Pablo Gómez de Liaño, Lucía; Martínez De La Casa Fernández-Borrella, José María; García Feijoo, Julián; Fernández Vigo, José ÁngelPurpose: To compare the behavior of aqueous humor (AH) and analyze flow differences by comparing the volume and velocity of the flow after two different models of implantable collamer lens (ICL) placement. Methods: Computational fluid dynamics with numerical simulation using Ansys Fluent software was performed to compare the AH flow through a peripheral iridotomy (PI), which is typically performed after implantation of a V4b lens to the central hole of a V4c lens. The volume and flow rate in 24 scenarios were compared according to the type of lens, pupil diameter (PD) (3.5 or 5.5 mm), the vault (100, 350, and 800 μm) and the PI (single or double, 180 or 360 μm). Results: With a standard vault (350 μm) and a PD of 3.5 mm, the volume of AH that flows from the posterior to the anterior chamber through the PI (V4b lens: 73.4% in 360 μm and 17.3% in 180 μm) and for the central hole (V4c lens: 75.7%) is larger than in the case of a PD of 5.5 mm (13.9%, 0.91%, and 15.3% respectively). When the vault is low (100; PD 3.5 mm), the volume of AH that reaches the central hole of the V4c lens is diminished (52.0%), being 5.1% if the pupil is enlarged. Conclusions: AH flow varies depending on the type of ICL implanted, whether it is implanted with an iridotomy or a central hole on the lens, the PD, and the vault.Item Changes in corneal biomechanical properties after 24 hours of continuous intraocular pressure monitoring using a contact lens sensor(Canadian Journal of Ophthalmology, 2017) Morales Fernández, Laura; García Bella, Javier; Martínez De La Casa Fernández-Borrella, José María; Sánchez Jean, Rubén; Sáenz Francés, Federico; Arriola Villalobos, Pedro; Perucho González, Lucía; Santos Bueso, Enrique Miguel; García Feijoo, JuliánObjective: This study was designed to assess changes in corneal topography and biomechanics after intraocular pressure (IOP) monitoring using the Triggerfish contact lens sensor (CLS). Methods: For this prospective study, 30 eyes of 30 subjects: 14 healthy subjects (G1) and 6 glaucoma patients (G2), were recruited for 24 hours of continuous IOP monitoring using the CLS. The following measurements were taken before CLS fitting and after lens removal: maximum keratometry (Kmax), mean keratometry (MK), and corneal astigmatism (Cyl) measured through Pentacam corneal topography, and the corneal biomechanical variables corneal hysteresis (CH) and corneal resistance factor (CRF) measured with the Ocular Response Analyzer (ORA). Results: Pentacam data revealed significant changes after CLS removal in Kmax (+3.14 ± 2.46 D, p = 0.002), MK (+0.52 ± 0.63 D, p = 0.02), and Cyl (+0.48 ± 0.53 D, p = 0.019) in G1; and Kmax (+1.38 ± 1.43 D, p = 0.002) in G2. The changes observed were more pronounced in G1 than in G2 but differences were not significant. The ORA results indicated higher CH (11.35 ± 2.42 vs 8.17 ± 2.09) and CRF (10.3 ± 2.03 vs 9.1 ± 1.81) before lens fitting in G1 than G2, while no significant changes were produced after CLS removal in either group. Conclusions: The use of CLS for IOP monitoring over 24 hours caused topographic changes in both healthy subjects and glaucoma patients. No changes were produced in corneal biomechanics.Item Visual outcomes after bilateral implantation of a new diffractive multifocal IOL: Preliminary results(2022) García Bella, Javier; Carballo Álvarez, Jesús; Collado Vincueria, Isabel; Sanz Fernández, Juan Carlos; García Feijoo, Julián; Martínez De La Casa Fernández-Borrella, José María; Vázquez Molini, José MaríaBackground: The aim was to determine visual outcomes and patient satisfaction in patients undergoing cataract surgery after the binocular implant of multifocal difractive Intensity IOL Methods: 21 patients were evaluated. Six weeks after surgery, uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA), distance corrected intermediate visual acuity at 60 cm(DCIVA) and distance corrected near visual acuity at 40cm (DCNVA) were determined using the ETDRS test. Defocus curves were produced both in photopic and mesopic conditions. Contrast sensitivity(CSF) was measured using the CSV-1000 test. Patients were shown pictures about dysphotopic phenomena and informed about their meaning with a likert scale from 0 (no problem) to 4 (overwhelming). Results: Post implantation mean logMAR Binocular UDVA, CDVA, DCIVA and DCNVA were 0.07± 0.09, -0.01 ± 0.04, 0.08 ± 0.05 and 0.12 ± 0.06 respectively. Photopic defocus curve showed a extended range of good vision. Mesopic defocus curve results were better than previously reported with trifocal designs. Mean binocular CSF values for 4 spatial frequencies (3, 6, 12 and 18 cpd) were 1.55±0.29, 1.60±0.17, 1.29±0.26 and 0.81±0.15 log. units, respectively. Halos were more frequent than starburst and glare with a Likert scale mean value of 0.86±0.83. Conclusions: The IOL provided a continuous range of vision from distance to near. Patients were not bothered or only slightly bothered in relation to the visual disturbances.
