PURPOSE: To assess the light reflex of the pupil after Implantable Collamer Lens (ICL) (KS-aquaPORT; STAAR Surgical, Nidau, Switzerland) implantation to determine whether the ICL implantation might affect the pupil dynamics. METHODS: This study examined 28 eyes of 28 consecutive patients who underwent implantation of the posterior phakic ICL for the correction of myopia and astigmatism. Patient age at the time of surgery was 31.1 ± 6.8 years (range: 25 to 42 years)...

BACKGROUND: To compare the outcomes of a toric phakic intraocular lens (PIOL) and a spherical PIOL combined with astigmatic keratotomy (AK) for the correction of high myopic astigmatism. METHODS: This study enrolled patients with high myopic astigmatism, including 30 eyes (22 patients) that received a toric PIOL implantation (TICL group), and 32 eyes (24 patients) that received combined AK and a spherical PIOL implantation (AK+ ICL group). The outcomes were compared between the two groups before surgery, and at the following time points after surgery: 1 week, 1, 3, 6 months, and 1, 2 years...

PURPOSE: To compare toric implantable collamer lens (T-ICL), femto-LASIK, and ReLEx SMILE for the treatment of low to moderate myopic astigmatism in terms of long-term visual and refractive outcomes and predictability of astigmatic correction. MATERIALS AND METHODS: The study included 30 eyes from 30 patients between the age groups of 21 and 40 years, undergoing bilateral surgery with any of the three procedures - T-ICL, femto-LASIK, or ReLEx SMILE - for correction of myopic astigmatism within the range of -3 to -8 D spherical equivalent (SE), with a minimum astigmatism of -0...

A 28-year-old lady with a refractive error of -11.0 D sphere/-1.50 D cylinder at 160 degrees in the right eye underwent an uneventful Implantable Collamer Lens surgery (ICL) with a V4c model, which uses a central Aquaport. This ICL does not require preoperative laser iridotomy or surgical iridectomy, as the centraflow opening is designed to prevent pupillary block. At postoperative day 1, her visual acuity in the right eye was 20/400, with diffuse microcystic corneal edema with fixed, dilated pupil and high intraocular pressure...

PURPOSE: To assess the predictability, efficacy, and safety of posterior chamber phakic implantable collamer lens (ICL) implantation after radial keratotomy. METHODS: In a retrospective non-comparative interventional case series, outcomes in 6 consecutive eyes of 4 patients with residual refraction after radial keratotomy were analyzed after the implantation of ICLs. All of the lenses were implanted to correct the residual refractive error, ranging from -12.00 to +3...

AIM: To evaluate the clinical outcomes of V4c implantable collamer lens (Hole ICL) implantation with regard to the optical quality assessed according to different degrees of decentering. METHODS: This included 49 eyes that received conventional ICL and 94 eyes that received Hole ICL. The eyes that received Hole ICL were divided into three groups according to the degree of decentering: group 1, central hole within 1 hole diameter (HD) from the pupil center; group 2, central hole within 1 HD to 2 HD; and group 3, central hole within 2 HD to 3 HD...

BACKGROUND: The limbal relaxing incisions (LRIs) technique is a safe and an inexpensive procedure, which is simple for experts to perform. It can effectively reduce astigmatism and result in a rapid visual rehabilitation. But there are few reports about reducing pre-existing corneal astigmatism by LRI in ICL surgery. Our research was aimed to study the effect of limbal relaxing inci sions during implantable collamer lens (ICL) surgery. METHODS: A prospective analysis reviewing consecutive cases of corneal astigmatism that had either independent ICL surgery (control group) or combined with LRIs (LRIs group)...

REVIEW
Jeewan S Titiyal, Manpreet Kaur, Ruchita Falera
Intraoperative optical coherence tomography (iOCT) is a noninvasive imaging modality that provides a real-time dynamic feedback of the various surgical steps. Comprehensive literature search was performed in MEDLINE using "intraoperative optical coherence tomography" and "iOCT" as keywords. The use of iOCT as an aid to decision-making has been successfully reported in cases undergoing keratoplasty, implantable Collamer lens (ICL) implantation as well as cataract surgery. iOCT helps to assess the graft-host relationship in penetrating keratoplasty...

PURPOSE: To evaluate long-term refractive outcomes of implantable collamer lens (ICL) implantation and late postoperative complications. METHODS: We assessed outcomes of patients who underwent ICL implantation (type ICM V4 for myopia, ICH V3 for hyperopia, TICM V4 for astigmatism) in our department between 1998 and 2013. It comprised 62 eyes (40 myopic and 22 hyperopic). The average follow-up period was 10.5 years. We evaluated: uncorrected and best-corrected visual acuity (UCVA and BCVA), spherical equivalent (SE), ICL vault, endothelial cell density and late postoperative complications...

PURPOSE: To determine whether posterior chamber phakic implantable collamer lens (ICL) surgery in high myopia patients impedes oxygen saturation of retinal vessels. METHODS: Mean oxygen saturation and diameter in retinal blood vessels were measured before and after ICL implantation surgery to correct high myopia refractive errors (i.e. -6.00 to -20.25 dioptres [D]), using an Oxymap T1 retinal oximeter. RESULTS: In 17 eyes of 17 patients, the Oxymap T1 retinal oximeter detected a small but significant decrease in oxygen saturation of retinal venules, 1-week postoperatively (compared to preoperative measurements)...

PURPOSE: To compare the efficacy and outcome of phakic toric implantable collamer lens (TICL) and refractive clear lens extraction with AcrySof Toric intraocular lens (TIOL) implantation for the treatment of myopic astigmatism. PATIENTS AND METHODS: This study assessed eyes with myopic astigmatism >-1 D and ≤-4 D with a spherical equivalent >10 D or <10 D if the patients were unsuitable for corneal refractive surgery. These eyes were divided into group A, in which Visian Toric ICL™ Phakic TICL was implanted, and group B, which involved clear lens extraction with implantation of an AcrySof IQ toric SN60T3-9™ IOL...

AIM: To assess the outcomes of posterior chamber implantable collamer lens (ICL) implantation in Chinese pediatric patients with unilateral high myopic amblyopia. METHODS: Eleven eyes of 11 amblyopic patients aged 11.02±3.34y underwent ICL (model V4, Staar Surgical Inc.) implantation to treat unilateral anisometropia were studied. Visual acuity, cycloplegic refraction, contrast sensitivity, stereopsis, intraocular pressure (IOP), vaulting, corneal endothelial cell count and complications were evaluated...

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...

AIM: To evaluate the etiology and management of elevated intraocular pressure (IOP) following posterior chamber phakic implantable collamer lens (ICL) surgery. METHODS: Between 2009 and 2015, 638 eyes of 359 subjects with refractive myopia, underwent V4b and V4c (CentraFLOW) model ICL implantation. Ocular hypertension (OHT) was defined as IOP of ≥ 22 mm Hg on two separate occasions and elevated IOP with corresponding optic disc or visual field damage was defined as glaucoma...
