“…These results are even better compared with those of other posterior chamber lenses. [18][19][20][21][22] Few short-term complications were observed, such as IOP increase during the first postoperative day because of residual viscoelastic 23 and during the first month because of corticosteroid response. Corticosteroids were used to prevent postsurgery inflammation, but it might instead to avoid this steroid side effect.…”

“…1,2 One is the thin and flexible ICL (implantable contact/corrective lens) (ICL by Staar Surgical, now Visian ICL), which is made of Collamer, a hydrophilic porcine collagen-hydroxyethyl methacrylate copolymer containing an ultraviolet chromophore. 3,4 Because refractive phakic lens surgery is minimally invasive, predictable, and stable, good results have been obtained with ICL implantation in hyperopic and myopic patients. 5 However, because it is intraocular surgery, phakic IOL implantation can cause complications.…”

The behavior of ICLs in relation to the crystalline lens during accommodation varied with age and could be shown by PCI. The position shift of the ICL depended on the initial vault at desaccommodation and the ability of the anterior lens surface to bulge forward. Even though the crystalline lens stiffened, and therefore accommodation deteriorated with age, there was still a movement of the ICL, pointing to the role of the ciliary muscle movement in accommodation.

“…One of the major postoperative complications of TICL use was high IOP [19], and the main reasons for high IOP in these patients were as follows: (1) sodium hyaluronate was intraoperatively left in the posterior chamber and pupil area, thus blocking the chamber angle; and (2) the use of steroids induced ocular hypertension. During the surgery, we used the I/A system (AMO phacoemulsification instrument).…”

With a rapid increase in the prevalence of Ultra-High Myopic Astigmatism (UHMA), especially in the youth, there have been many studies on visual correction. In our study, we investigated the clinical value of the Toric Implantable Collamer Lens (TICL) in UHMA. We conducted a retrospective study between 2011 and 2013. TICL implantation was performed on fifteen UHMA patients (30 eyes), and all these patients were regularly followed up for 12 months. The preoperative and postoperative data, including Uncorrected Visual Acuity (UCVA), Best Corrected Visual Acuity (BCVA), Intraocular Pressure (IOP), and corneal endothelial counts, were all analysed using the paired-sample t-test. The 12-month spherical mirror (SPH) of the surgical eye was -0.25~+0.25 D, and the Cylinder mirror (CYL) was 0~-0.50 D. Twenty patients exhibited an increase in UCVA by one level in comparison to the preoperative BCVA, amounting to a 66.7% increase; 20.0% of patients exhibited an increase in UCVA by two levels. A comparison between the preoperative and postoperative IOP showed no statistically significant difference. No difference was also found in mean corneal endothelial counts before and after the operation. A decrease in visual acuity was observed in one eye at the 3 rd -month of review; this was corrected by TICL position adjustment. Precisely measuring the preoperative parameters, selecting the appropriate TICL, more thoroughly aspirating sodium hyaluronate intraoperatively, and maintaining a stable IOP were important for maintaining the effectiveness, safety and stability of TICL in treating UHMA.
