Abstract
Purpose: To analyze the factors related to corrected distance vision acuity (CDVA) after implantable collamer lens (ICL) implantation in patients with preoperative suboptimal CDVA.Methods: This retrospective study included patients with suboptimal preoperative CDVA (CDVA ≤20/25) who underwent ICL implantation (V4 or V4c). Preoperative and postoperative clinical evaluations included CDVA, uncorrected distance visual acuity (UDVA), and refraction.Results: A total of 1,212 eyes from 731 patients were identified. CDVA increased in 90.8% of the eyes after surgery. Among them, 57.5% of the eyes (697 eyes) gained more than one line. The preoperative LogMAR CDVA was 0.32 ± 0.23, which significantly improved to 0.13 ± 0.17 postoperatively (p < 0.001). There was no significant difference between ICL V4c and ICL V4 in the LogMAR UDVA, sphere, cylinder, SE, LogMAR CDVA, efficacy index, and safety index after surgery (p > 0.05). For eyes with full correction, the postoperative LogMAR CDVA =0.575 * preoperative LogMAR CDVA -0.061 (p < 0.001, R2 = 0.53). For eyes with partial correction, the postoperative LogMAR CDVA =0.536 * preoperative LogMAR CDVA - 0.007 * SE - 0.196 (P < 0.001, R2 = 0.55).Conclusion: ICL implantation can improve CDVA in eyes with suboptimal CDVA. This study provides the postoperative outcomes of eyes with different preoperative CDVA, which makes it convenient for surgeons to communicate with such patients before surgery.

Int Ophthalmol 2021; 41:2837-2845. [PMID: 33864187 DOI: 10.1007/s10792-021-01841-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Accepted: 04/01/2021] [Indexed: 11/27/2022]
Abstract
PURPOSE Evaluating efficacy and safety of iris-supported phakic lenses (Verisyse) for high myopia treatment. METHODS Patients treated with Verisyse (Abbott Medical Optics, Santa Ana, CA, USA) intraocular lens (IOL) implants were evaluated retrospectively. Patients with follow-up periods of more than 5 years were included in the study. Pre- and postoperative fifth-year spheric equivalent (SE) of manifest refraction values, uncorrected and corrected distance visual acuities (UDVA and CDVA, respectively), and endothelial cell density (ECD) values were recorded. Complications were evaluated. RESULTS Forty-seven eyes of 31 patients were included in the study. Pre- and postoperative fifth year mean SE was - 12.50 ± 3.51D and - 0.72 ± 0.40D, respectively. Pre- and postoperative fifth-year UDVA was 1.56 ± 0.22 and 0.33 ± 0.18 logMAR (p < 0.001), respectively. The safety index (pre- and postoperative CDVA) was 1.39 ± 0.63 at the 5-year follow-up (p > 0,05). The efficacy index (ratio of mean postoperative UDVA to mean preoperative CDVA) of the patients was 1.14 ± 0.60. The mean postoperative endothelial cell loss at 5 years was -7.42%. None of the patients had lost 25% of their preoperative endothelial cells at 5-year follow-up. The mean postoperative endothelial cell loss was -3.05% at 1 year, -1.23% between years one and three, -1.02% between the third and fifth years. CONCLUSION Verisyse IOL implantation is an effective and safe for high myopia surgical treatment. However, the 5-year follow-up period is not sufficient to evaluate the safety profiles in terms of endothelial cells.

Abstract
PURPOSE To evaluate the visual outcomes of laser vision correction in adults with myopic and hyperopic amblyopia. METHODS The medical records of patients diagnosed as having amblyopia who underwent laser refractive surgery between February 2013 and October 2017 were retrospectively reviewed. Eyes with amblyopia were analyzed, and the nonamblyopic fellow eyes of the patients who underwent laser vision correction were used as controls. The uncorrected distance visual acuity (UDVA), subjective manifest refraction, and corrected distance visual acuity (CDVA) were analyzed at the 3-month postoperative time point. RESULTS This study included 323 eyes of 164 patients. All patients underwent laser in situ keratomileusis (90.1%, 291 eyes) or photorefractive keratectomy (9.9%, 32 eyes). Three months postoperatively, the manifest spherical equivalent was -0.07 ± 0.55 diopters (D) (range: -1.75 to +1.30 D) and -0.10 ± 0.54 D (range: -2.13 to +1.30 D) in the amblyopia group and fellow eye group, respectively. The percentage of eyes achieving UDVA of 20/20 or better was 16.9% (15 eyes) in the amblyopia group and 61.9% (52 eyes) in the fellow eye group. The percentage of eyes that gained two or more lines of CDVA was 27.9% (24 eyes) in the amblyopia group and 6.2% (5 eyes) in the fellow eye group (P < .01). In the amblyopia group, there was no statistically significant difference in the mean manifest spherical equivalent between the myopic eyes and hyper-opic eyes at any follow-up visit (P = .87, 1 month postoperatively; P = .68, 3 months postoperatively). CONCLUSIONS Laser vision correction was found to be effective and safe in adult patients with amblyopia. [J Refract Surg. 2020;36(8):511-519.].

Abstract
This study aims to evaluate the clinical results of posterior chamber implantable collamer lens (ICL) implantation in adults with high myopic anisometropic amblyopia. Thirteen patients aged 27.04±7.24y (range 19.2 to 42.5) were studied. ICL implantation was performed in 13 amblyopic eyes. The mean myopic anisometropia was significantly dropped from -10.70±3.02 D preoperatively to +0.09±1.67 D at 1mo postoperatively. The logMAR CDVA at 3d, 1, 3 and mean 9mo postoperatively improved by a mean of 1.69, 2.50, 3.01 and 3.00 lines and gained more than 2 lines accounted for 23.08% (3 eyes), 41.67% (5 eyes), 63.63% (7 eyes) and 55.56% (5 eyes), respectively. The contrast sensitivity of amblyopic eyes was significantly increased after surgery. Four patients partially recovered near stereopsis (400″ to 100″). There was no severe complications were observed. ICL implantation alone can improve vision, contrast sensitivity, and partial restoration of binocular vision in adult patients with high myopic anisometropia.

Verisyse versus Veriflex Phakic Intraocular Lenses: Refractive Outcomes and Endothelial Cell Density 5 Years after Surgery. J Ophthalmol 2018; 2018:4210460. [PMID: 30363928 PMCID: PMC6186327 DOI: 10.1155/2018/4210460] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Revised: 08/11/2018] [Accepted: 08/26/2018] [Indexed: 11/25/2022] Open
Abstract
Purpose To compare refractive stability, central endothelial cell density (ECD), and complications between Verisyse (Abbott Medical Optics, Netherlands) and Veriflex (Abbott Medical Optics, Netherlands) phakic intraocular lenses (pIOL) over five years. Methods We retrospectively reviewed the medical records of patients who underwent Verisyse or Veriflex pIOL implantation for surgical correction of myopia. Patients with a 5-year follow-up period were included in the study. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical equivalent of manifest refraction (SE), and ECD were compared between the groups preoperatively and 1, 3, and 5 years postoperatively. Results The study included 47 eyes in the Verisyse group and 50 eyes in the Veriflex group. There was no significant difference in mean SE, UDVA, CDVA, and ECD preoperatively or postoperatively. In both groups, there was a statistically significant myopic shift between 1-year and 5-year visits (−0.25 ± 0.30 D and −0.23 ± 0.48 D in the Verisyse and Veriflex groups, respectively). There was no significant difference between the groups in terms of efficacy and safety indexes at 5 years. ECD loss was highest during the first year (3.9% loss in the Verisyse group and 3.9% loss in the Veriflex group, p=0.670). At 5 years, the mean cumulative ECD losses in the Verisyse and Veriflex groups were 7.42% and 7.64%, respectively (p=0.709). Cataracts developed in 2.1% of the eyes in the Verisyse group and in 2.0% of those in the Veriflex group. No sight-threatening complications were observed. Conclusion Verisyse and Veriflex pIOLs are highly effective for treating high myopia up to 5 years after surgery. Longitudinal studies with longer follow-up periods are necessary to determine the endothelial safety profile.

Abstract
Purpose To report clinical results of a foldable, hydrophilic acrylic, single-piece, injectable, posterior chamber phakic intraocular lens (pIOL). Material and Methods Medical records of patients who underwent posterior chamber phakic IOL (Eyecryl Phakic IOL, Biotech Vision Care, Ahmedabad, India) implantation for surgical correction of myopia were retrospectively reviewed. Only patients with at least a one-year follow-up were included. Manifest refraction, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), endothelial cell density (ECD), and pIOL vault were analyzed at 1, 3, 6, and 12 months after surgery. Complications observed during and after surgery were also recorded. Results The study included 58 eyes of 29 patients. Mean patient age was 32 ± 7 years. Spherical equivalent of manifest refraction was −13.41 ± 3.23 D preoperatively and −0.44 ± 0.55 D postoperatively. Preoperative CDVA was 0.29 ± 0.71 logMAR. Postoperative UDVA and CDVA were 0.21 ± 0.66 and 0.15 ± 0.69 logMAR, respectively, at the 12-month visit. At the 12-month visit, the efficacy index was 1.20 and the safety index was 1.39. Mean ECD was 2713 ± 339 cells/mm2 at the preoperative visit and 2608 ± 362 cells/mm2 at the 12-month visit (3.9% loss, p < 0.001). ECD loss from 3 months to 12 months was not statistically significant. No significant cataract formation, significant endothelial cell loss, glaucoma, uveitis, or any other vision-threatening complication was observed. Conclusion Based on postoperative experience, we have found that Eyecryl Phakic IOL is safe and effective for treating high myopia.

Abstract
To characterize a complex of disorders developing in patients with extreme values of anteroposterior axis of the eye, it is necessary to create an appropriate nomenclature. As a topic for discussion, authors suggest to supplement the existing classifications of myopia and hyperopia with 'character of ametropia' section (axial, refractive, mixed) and the definition of ametropias of very high (ultra-high/extreme) degree (a criterion for myopia is: <-10 D). In prospect, classification of such ametropias should be based on the length of the anteroposterior axis of the eye.

Abstract
OBJECTIVE Case series of haptic migration in patients with angle-supported phakic anterior chamber intraocular lens (PAC-IOL: Phakic6H) through the superior peripheral iridectomy (PI). METHODS Charts of 23 patients (35 eyes) with at least 6 months' postoperative follow-up were retrospectively reviewed. Evaluation included preoperative and postoperative cycloplegic and manifest refractions, uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), slit-lamp examination, fundoscopy, corneal topography, and biometry. RESULTS Mean UCVA was 1.67 ± 0.30 (1.17-2.00) for all 35 eyes preoperatively and 0.35 ± 0.25 (0.00-1.00) postoperatively (p < 0.001; 95% CI 1.21-1.44). BCVA had a mean of 0.31 ± 0.26 for all 35 eyes preoperatively, and a mean of 0.22 ± 0.25 postoperatively (p < 0.001; 95% CI 0.04-0.14). Haptic migration into the superior PI was noted in 8 eyes (23%). The first migration was noted 2 years postoperatively and the last 8 years after implantation (mean, 5.6 ± 2 years). There was no statistically significant difference in the BCVA and UCVA before and after haptic migration. Follow-up ranged from 8 months to 8.5 years. CONCLUSIONS Angle-supported PAC-IOL implantation resulted in significant improvement in both UCVA and BCVA. However, there is a 23% incidence of haptic migration in our series with no sequelae on BCVA or harmful effect on the intraocular structures. This IOL movement may be explained by changes in aqueous dynamics at the level of the PI leading to migration of the haptic into the area of least resistance.

Abstract
Purpose. To analyze the safety, effectiveness, and stability of triplex surgery for phakic 6H anterior chamber phakic intraocular lens explantation and phacoemulsification with in-the-bag IOL implantation for super high myopia in long-term observations. Methods. This retrospective case series evaluated 16 eyes of 10 patients who underwent triplex surgery. Best corrected visual acuity (BCVA), endothelial cell density (ECD), and associated adverse events were evaluated. Results. The mean follow-up time after the triplex surgery was 46 ± 14 months. The mean logMAR BCVA was significantly improved after triplex surgery (P = 0.047). One eye developed endophthalmitis five days postoperatively and underwent pars plana vitrectomy (PPV). Five eyes with preoperative severe endothelial cell loss developed corneal decompensation and underwent keratoplasty at a mean time of 9.4 ± 2.6 months after the triplex surgery. One eye had graft failure and underwent a second keratoplasty. The eye developed rhegmatogenous retinal detachment and underwent PPV with silicone oil 18 months later. ECD before the triplex surgery was not significantly different compared with that at last follow-up (P = 0.495) apart from these five eyes. Three eyes (18.8%) developed posterior capsule opacification. Conclusions. Triplex surgery was safe and effective for phakic 6H related complicated cataracts. Early extraction before severe ECD loss is recommended.

Abstract
PURPOSE The aim of this study was to evaluate a clinical procedure based on trial rigid gas-permeable (RGP) contact lenses fitting to assess the real pre-operative visual acuity (VA) of highly myopic eyes undergoing surgery with an implantable collamer lens. METHODS Highly myopic eyes with a spectacle visual acuity (SVA) of 0.2 logMAR (6/9.6 Snellen) or worse were enrolled. A trial RGP contact lens with high dioptric power was fitted before collamer lens implantation. The trial contact lens residual refractive error was corrected by spectacle over-refraction to estimate contact lens VA (CLVA). The three-month post-operative uncorrected vision and visual acuities were also measured. The safety and efficacy indices of collamer lens implantation were calculated based on pre-operative SVA and CLVA, respectively. RESULTS The study enrolled 42 patients with 68 highly myopic eyes with a mean pre-operative spherical equivalent of -16.40 ± 4.43 D. The mean pre-operative SVA was 0.38 ± 0.19 logMAR. Pre-operative trial RGP contact lens fitting resulted in a significant improvement of VA (2.02 ± 1.05 lines), which was statistically insignificantly different from the VA with the implantable collamer lens (2.07 ± 0.8 lines). The safety index of collamer lens implantation was 1.70 ± 0.38 in reference to the pre-operative SVA but significantly decreased to 1.02 ± 0.17 in reference to CLVA. Similarly, the efficacy index of 1.17 ± 0.48 on SVA decreased to 0.71 ± 0.28 on CLVA. CONCLUSIONS Trial RGP contact lens fitting was found to indicate the potential implantable collamer lens VA more accurately than spectacle refraction. Consideration should be given to the use a trial RGP contact lens as part of the pre-operative work-up prior to collamer lens implantation in order to provide an assessment of the patient's potential post-operative VA.

Abstract
We assessed the outcomes of the use of anterior chamber foldable lens for unilateral aphakia correction at the University Teaching Hospital of Yaounde. In this retrospective, non-comparative, consecutive case series study, we reviewed the records of patients who underwent an operation for aphakia correction by the means of injection of an angular supported foldable lens between January 2009 and December 2011 in the University Teaching Hospital Yaounde. Student's paired t-test was carried out to compare pre-operative and post-operative visual acuity (VA) and intraocular pressure (IOP). P-values less than 0.05 were considered statistically significant. Twenty-one patients were included in the study; twelve were male (57.1%) and nine were female (42.9%). The mean age was 55.38 ± 17.67 years (range 9-75 years). The mean follow-up duration was 5.95 ± 3.14 months (range 2-12 months). The mean log-MAR visual acuity was 1.26 ± 0.46 pre-operatively and 0.78 ± 0.57 post-operatively (P = 0.003). The change in intraocular pressure was not statistically significant. Complications included intraocular hypertension (over 21 mmHg) in 3 patients (14.3%) and macular edema, pupillar ovalization, and retinal detachment in one patient each. The results indicate that injection of an angular support foldable lens in the anterior chamber is a useful technique for the correction of aphakia in eyes without capsular support. More extended follow-up, however, and a larger series of patients are needed to ascertain the effectiveness and safety of this procedure.
