“…The postoperative UCVA and BCVA were −0.03 ± 0.08 LogMAR and −0.03 ± 0.07 LogMAR, respectively. The efficacy index and safety index were 1.27 and 1.28, respectively, which were consistent with previous studies [9, 12–14]. These findings suggest that V4c-ICL is a safe and effective treatment for high myopia, and it significantly simplifies the ICL implantation procedure.…”

The new type implantable Collamer lens with a central hole (V4c-ICL) is widely used to treat myopia. However, halos occur in some patients after surgery. The aim is to evaluate the effect of V4c-ICL implantation on vision-related daily activities. This retrospective study included 42 patients. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), intraocular pressure (IOP), endothelial cell density (ECD), and vault were recorded and vision-related daily activities were evaluated at 3 months after operation. The average spherical equivalent was −0.12 ± 0.33 D at 3 months after operation. UCVA equal to or better than preoperative BCVA occurred in 98% of eyes. The average BCVA at 3 months after operation was −0.03 ± 0.07 LogMAR, which was significantly better than preoperative BCVA (0.08 ± 0.10 LogMAR) (P = 0.029). Apart from one patient (2.4%) who had difficulty reading computer screens, all patients had satisfactory or very satisfactory results. During the early postoperation, halos occurred in 23 patients (54.8%). However there were no significant differences in the scores of visual functions between patients with and without halos (P > 0.05). Patients were very satisfied with their vision-related daily activities at 3 months after operation. The central hole of V4c-ICL does not affect patients' vision-related daily activities.

“…The ICL implantation with the standard method has proved to be an effective, safe, and predictable surgery for myopia correction [24,[28][29][30]. In our study, the LogMAR CDVA at 3 months after surgery was significantly improved with the safety index to be 1.18 in the OVD-free method group and 1.23 in the standard method group.…”

“…Alfonso et al [24] reported 8.5% endothelial cell loss 6 months postoperatively. Lisa et al [29] found a mean endothelial cell loss of 1.7% at 12 months postoperatively. In the OVD-free method group, a 4.6% endothelial cell loss at 3 months was comparable with the results from previous studies which used the standard method.…”

“…The long-term complications of the OVD-free method could mostly be identical to the standard method because the ICL model (V4c) and position of implantation (posterior chamber) were the same in both groups. The long-term complications after ICL implantation with standard method have been fully evaluated by several studies [29,30], therefore, the intraoperative complications and short-term complications should be a major concern in the current study so as to investigate efficacy and safety of a newer surgical technique. The current study has demonstrated that all surgical procedures were performed uneventfully, and no pupillary block, cataract formation or pigment dispersion syndrome was seen during the 3-month observation period.…”

Purpose: To assess the efficacy and safety of a novel ophthalmic viscosurgical device-free (OVD-free) method for posterior chamber phakic intraocular lens (PIOL) implantation in myopic eyes. Methods: In this retrospective cohort study, the medical records of myopic eyes that underwent PIOL (Implantable Collamer Lens, ICL) implantation for myopia correction at the Eye Hospital of Wenzhou Medical University between May 2015 and March 2017 were reviewed. A total of 49 eyes with complete data that met follow up requirements (2 h, 1 day, 1 week, 3 months postoperatively) were recruited. Based on the surgical techniques used, the eyes were divided into the OVD-free method group and the standard method group. The clinical data, including intraocular pressure (IOP), corrected distance visual acuity (CDVA) and spherical equivalent (SE), at each follow-up were collected for comparison. Endothelial cell loss and complications were also investigated. Results: Twenty-one eyes received the standard method, and 28 eyes received the OVD-free method. A rise in IOP > 22 mmHg at 2 h was noted in 14 eyes (66.7%) in the standard group and none (0%) in the OVD-free group (p < 0.001). The rise in IOP from baseline was significantly higher at 2 h in the standard group (10.5 ± 5.2 mmHg vs. 2.2 ± 3.3 mmHg, difference: 8.3, 95% CI 5.8 to 10.8; p < 0.001). There was a significant difference in the time course of LogMAR CDVA changes between the two groups (p = 0.047). The LogMAR CDVA was significantly better in the OVD-free method group compared to the standard group at 1 day (− 0.076, 95% CI − 0.134 to − 0.018; p = 0.012), 1 week (− 0.071, 95% CI − 0.135 to − 0.007; p = 0.03), but not at 3 months (− 0.046, 95% CI − 0.107 to 0.015; p = 0.134). There was no significant difference in the time course of SE changes between the two groups (p = 0.471; p = 0.705). In the OVD-free group, mean endothelial cell loss was 4.6% at 3 months (2522 ± 281 vs. 2407 ± 226 cells/ mm 2 , difference:-115, 95% CI − 295 to 65; p = 0.187). No complications were reported in both groups except for the early IOP elevation in the standard group during the observation period. Conclusions: The OVD-free method is safe and efficient for ICL implantation. It can be a safer method of ICL implantation compared to the standard method in that it completely eliminates ophthalmic viscoelastic devicesrelated complications without causing additional complications.

“…At present, the ICL V4c decreases the rate of opacity and intraocular pressure increase without peripheral iridotomy because of the central hole design. Besides, pupil capture rarely occurs as the ICL haptics were placed in the ciliary sulcus [14,15].…”

I examined a 36 year old pseudophakic male patient with ectopic pupil, high myopia and astigmatism in left eye at December 2017, He had an ophtalmic surgery history before he came to me, First one had an extracapsular cataract extraction and PMMA iol implantation into his left eye in 14 years old hence blunt eye trauma. Four years after this operation he had to go bilateral strabismus surgery for divergent strabismus probably due to low vision. He came to me after 18 years from his last operation with the intend of a good vision without glasses or contact lenses. His visual acuity was 18/20 in right eye and counting fingers from 2 meters in left eye without correction. As for with glasses 20/20 in right eye with-0.25(-0.25x180) and 2/20 in left eye with-7.25(-3.25x170), Intraocular pressure (IOP) was 12 mmHg in both eyes. Then the left eye was implanted posterior chamber VTICMO13.7 Staar Toric ICL. Even in the first postoperative day his refraction was +1(-2,00x20) and uncorrected distance visual acuity UDVA was 10/20 whereas corrected distance visual acuity CDVA was 16/20. IOP was 18mmHg and no complications were detected.
