“…[39] The correct size of the phakic IOL can only be determined by measuring the horizontal WTW and ACD values. [40] The accuracy of vault prediction is enhanced by using various ophthalmic devices to obtain more detailed anatomic dimensional parameters, such as angle-to-angle, anterior chamber area, and ciliary sulcus diameter. [41] The ideal vault value for ICL is between 500 and 700 µm.…”

This study aimed to compare the postimplantation clinical outcomes of 2 types of posterior chamber phakic intraocular lenses (IOLs): Visian™ implantable collamer lenses (ICL; EVO+ V5; Staar Surgical, Monrovia, CA) and an implantable phakic contact lens (IPCL) (IPCL V2.0, Care Group Sight Solution, India) to correct high myopia and myopic astigmatism. This retrospective study included patients who had undergone phakic IOL implantation performed by a single surgeon between March 2021 and March 2022. Preoperative assessments included slit-lamp examination, fundus examination, spherical equivalent, uncorrected distant visual acuity (UDVA), corrected distant visual acuity (CDVA), specular microscope parameters, and optical quality analysis system parameters. Postoperative assessments after 1 year included slit-lamp examination to detect adverse effects and spherical equivalent, UDVA, CDVA, specular microscope, optical quality analysis system, and anterior-segment optical coherence tomography. Eighty eyes from 42 patients (47 eyes from 24 patients in the ICL group and 33 eyes from 18 patients in the IPCL group) were included. No statistically significant differences were observed between the 2 groups regarding preoperative parameters. At 1-year postoperatively, the mean UDVA in the ICL and IPCL groups was 0.019 ± 0.040 logMAR and 0.019 ± 0.041 logMAR, respectively. The mean CDVA was 0.001 ± 0.008 logMAR and 0.001 ± 0.007 logMAR in the ICL and IPCL groups, respectively, showing no statistically significant differences. The postoperative parameters did not differ significantly between the 2 groups. The visual acuity and refractive results of both groups were excellent, and both groups exhibited similar efficacy and safety profiles.

“…The studies referring to Artisan refer to e cacy indices at one year between 0.79 and 1 [33,34]. Cakir et al [35], in a review of 5-year results, concluded that Artisan IOL implantation is an effective and safe procedure for the surgical treatment of high myopia. A similar conclusion is drawn in Monteiro et al [36] and Charters et al [37], referring that phakic intraocular lenses are extremely useful in high myopia and an excellent addition to refractive armamentarium in clinical practice.…”

Background To evaluate the efficacy and safety of Femto-LASIK, PRK, and Artiflex/Artisan phakic lens implantation in the surgical correction of myopia at three months, one, two, and five years of follow-up. Methods A retrospective study was proposed in patients who underwent Femto-LASIK technique (287 eyes of 171 patients), PRK (245 eyes of 191 patients), and phakic lens implantation (147 patient eyes) between 2010-2011 with a preoperative spheric equivalent greater than -6 diopters. The effectiveness and safety indexes were calculated during follow-up, comparing Femto-LASIK, PRK, and Artiflex/Artisan phakic lens implantation. In addition, a multivariate linear regression model was estimated. Results There were statistically significant differences in effectiveness and safety until five years when comparing Artiflex/Artisan versus PRK and Femto-LASIK (p<0.01). A linear regression model has established whose dependent variable was the UCVA at five years and independent variables were spherical equivalent preop, phakic lens implantation, and PRK. The model explained 30.32% of the patients' visual acuity variability at five years. Conclusions Artiflex/Artisan type phakic lens implantation is an effective, safe, and predictable technique at three months, 1, 2, and 5 years with stable refractive results throughout the follow-up periods compared with PRK surgery and Femto-Lasik. The model presented shows phakic lens surgery increases the UCVA result at five years and surgery with PRK decreases this final result.

Background. This study aimed to compare the efficacy and safety of Femto-LASIK, PRK, and Artiflex/Artisan phakic lens implantation in the surgical correction of myopia at different moments of postoperative follow-up; to propose a linear predictive model of visual acuity without correction at five years of refractive procedures; and to evaluate its validity. Methods. A retrospective observational analysis was performed. Patients were clinically reviewed after three months, one year, two years, and five years. Univariate and bivariate analyses and a multivariate linear regression model were performed. Results. Six hundred seventy-nine eyes were analyzed: 18.9% Artiflex, 2.8% Artisan, 42.3% Femto-LASIK, and 36.1% PRK. There were significant differences in effectiveness and safety after five years when comparing Artiflex/Artisan versus PRK and Femto-LASIK (p < 0.01). The linear regression model explained 30.32% of the patients’ visual acuity variability after five years. Conclusions. PRK surgery, Femto-Lasik, and Artiflex/Artisan type phakic lens implantation are effective, safe, and predictable techniques with stable refractive results. Phakic lenses magnify myopic patients who improve their UCVA and BCVA. Concerning phakic lens implantation, corneal endothelial cells remain stable. The predictive model calculated that surgery with a phakic lens increased the UCVA result at five years, and surgery with PRK slightly decreased the long-term results.
