“…Similarly, Gonvers et al [ 24 ] found higher incidence of cataract development in older patients (14% of the younger patients [10 to 40 years] versus 37% of the older patients [41 to 50 years]). Choi et al [ 25 ], in a 10-year clinical study ( n = 110), found lens opacities in 21 eyes (12.1%) and the mean age at which lens opacity was first observed was 48.7 ± 7.1 years. They found a difference in the preoperative age between the clear lens group and lens opacity group as well as a higher cumulative incidence of lens opacity in patients with higher preoperative age.…”

Purpose. To assess the efficacy, safety, and predictability of the Visian Implantable Collamer Lens (ICL) model having a central port in patients over 40 years of age. Methods. This study included 33 eyes from 21 patients who underwent V4c ICL implantation for the correction of myopia and myopic astigmatism. We assessed uncorrected (UDVA) and corrected (CDVA) distance visual acuity, refraction, intraocular pressure (IOP), endothelial cell density (ECD), vault, and adverse events occurring over a 1-year period. Results. Mean age of the patients at the time of implantation was 43.52 ± 4.49 years (range: 40 to 56 years). Efficacy and safety indexes were 1 and 1.09, respectively. Surgical outcomes for CDVA were as follows: no eye lost any lines, 19 eyes (57.58%) showed no CDVA changes, 7 eyes (21.21%) gained 1 line, 4 eyes (12.12%) gained 2 lines, and 3 eyes (9.09%) gained ≥3 lines. Mean postoperative spherical equivalent (SE) was −0.09 ± 0.47 D. A total of 29 eyes (87.8%) were within ±0.50 D and 31 eyes (93.9%) were within ±1.00 D of the desired SE. At 1-year, mean IOP was 15.27 ± 3.03 mmHg (range: 9 to 20 mmHg, p=0.12 pre vs. post) and mean ECD was 2516 ± 234 cells/mm2 (p=0.29 pre vs. post). Mean postoperative vault was 320 ± 136 μm, with 201–300 μm being the most prevalent vault range for 9 eyes (31.03%). None of the eyes showed a vault >701 μm. There were neither intraoperative nor postoperative complications; in fact, all ICL implantation procedures were uneventful. Conclusions. Our study’s findings support the use of this lens in patients over 40 years of age. A long follow-up period is advisable to monitor ICL position relative to the crystalline lens.

“…Choi comes, including efficacy and safety, of implantable collamer lens (ICL) implantation to treat myopia. 31 The results indicated that ICL implantation provided long-term stability and good refractive outcomes. Performing this surgery in young patients, especially those 30 years or younger, may be safe in terms of long-term cataract formation.…”

“…With appropriate management, most cases were transient, and the IOP remained stable during follow-up. Chronic IOP elevation was less frequently reported in the literature, and its reported incidence ranges from 0-12.9% [2][3][4][5][6][10][11][12]. Sánchez-Galeana et al [13] reported a case of refractory IOP elevation with significant pigment dispersion following ICL implantation.…”

“…IOP was uncontrollable with medical therapy, and ICL explantation and trabeculectomy were performed. Choi et al [6] reported another case of pigmentary glaucoma after ICL surgery. In that case, glaucoma filtration surgery was performed 5 years after ICL implantation without ICL removal.…”

“…Since its first implantation in 1993, multiple revisions have been made in material and design to increase applications and minimize complications [1]. Clinical investigations have demonstrated that ICL implantation provides satisfactory refractive outcomes and long-term stability [2][3][4][5][6]. Although relatively safe, ICL implantation is associated with complications, such as postoperative intraocular pressure (IOP) elevation, cataract formation, and corneal endothelial cell loss [7].…”

Background Implantation of the posterior chamber phakic intraocular lens has been widely performed to correct high and extreme myopia. Chronic intraocular pressure (IOP) elevation may occur in its late postoperative period. For medically uncontrolled cases, surgical treatment is necessary, and benefits should be weighed against risks when determining whether to remove the lens. Case presentation A 32-year-old man with extremely high myopia presented with progressive blurred vision and medically uncontrolled IOP in the right eye. His past ocular history was significant for bilateral implantable collamer lens (ICL) implantation ten years ago. On ophthalmic examination, the ICL was well placed with a vault height of 456 µm in the right eye. The anterior chamber angles were open but narrow, and mild to moderate trabecular pigmentation was noted. Ex-PRESS glaucoma filtration surgery without ICL removal was performed to control IOP. During surgery, an Ex-PRESS P50 shunt was inserted into the anterior chamber via the front edge of the blue-grey transition zone between the sclera and cornea. Transient hypotony and shallow anterior chamber occurred in the first week after surgery, along with an ICL tilt towards the cornea with reduced vault height. No other complications related to either the ICL or the Ex-PRESS shunt were noted. IOP remained stable at 12 ~ 14 mmHg at the first 3-month follow-up. Conclusions Ex-PRESS glaucoma filtration surgery might be a safe and effective alternative treatment for intractable glaucoma with high myopia and ICL implantation. Careful assessment of the ICL position and anterior chamber angle is necessary to plan the appropriate surgical procedure. A postoperative shallow anterior chamber may result in ICL dislocation.
