BACKGROUND: An investigation was carried out to find the distribution of central corneal thickness (CCT) and the association between CCT and ocular factors in a cohort of myopic Chinese adults who underwent laser refractive surgery. METHODS: Medical records of 1,190 subjects (754 males) aged from 18 to 44 years (21.5 ± 3.5 years for males and 24.9 ± 5.5 years for females) undergoing myopic refractive surgery were filtered and analysed. Each parameter was stratified by gender and eye, respectively...

Posterior capsule rupture with herniated lens fragment in the vitreous cavity on magnetic resonance imaging has not been reported in India until now; however, it has been reported in other countries. Therefore, this study reports the case of a 15-year-old boy presenting with posttraumatic loss of vision in the right eye due to posterior capsular rupture and herniation of lens material into the vitreous cavity, which was detected by B-scan ultrasonography and magnetic resonance imaging as no ophthalmic examination was possible due to the posttraumatic cataract...

BACKGROUND: To compare refractive outcomes after cataract surgery between patients with closed-angle and open-angle glaucoma and evaluate the influence of preoperative factors on refractive outcomes in patients with glaucoma. METHODS: Patients diagnosed with glaucoma and who underwent uncomplicated cataract surgery were enrolled in this retrospective observational study. We collected data including age, history of prior laser peripheral iridotomy and trabeculectomy, type of glaucoma, manifest refraction, intraocular pressure, axial length, and various anterior segment parameters using anterior-segment optical coherence tomography...

Positive vitreous pressure (PVP) occurs during anterior segment intraocular surgery associated with acute hypotony and is characterized by forward displacement of the lens-iris diaphragm with shallowing of the anterior chamber resistant to reformation, repeated iris prolapse, and, in severe cases, zonular rupture and vitreous or lens prolapse that can lead to a cascade of intraoperative complications. PVP is particularly common during penetrating keratoplasty (PK), conventional nuclear expression cataract extraction, and repair of anterior open globe injury...

AIM: To evaluate the visual and topographic outcomes of a two-stage approach treatment for selected cases of progressive keratoconus (KC); corneal collagen cross-linking (CXL) followed by phacoemulsification with toric intraocular lens (IOL) implantation. METHODS: The study included 9 eyes of 6 patients diagnosed with progressive KC, aged from 35 to 47 years (41.6±11.2 years). All studied eyes underwent a two-stage approach treatment: first corneal collagen CXL followed after at least 6 months by phacoemulsification with foldable toric IOL implantation in both eyes of three patients and only one eye of the other three patients...

PURPOSE: The study was performed to study the effect of cycloplegia on anterior chamber depth (ACD) in cataract eyes. One instrument (Lenstar) was used for all measurements. METHODS: Anterior chamber depth calculations were taken with the Lenstar in cataract eyes with a mean age of 71.9±8.8 years before instilling cycloplegic drops. Two drops of Tropicamide were then instilled in each eye and measurements were retaken between 30 to 45 min later. RESULTS: Cycloplegia with a mild agent used routinely in this practice location showed a statically significant effect on increasing ACD by 0...

PURPOSE OF REVIEW: This article describes different strategies for corneal measurements and/or intraocular lens (IOL) calculations and proposes a systematic approach for IOL selection in patients who have undergone laser corneal refractive surgery. RECENT FINDINGS: Corneal measurements and IOL calculations cannot be obtained accurately with the standard measuring technologies and formulas in patients with history of laser corneal refractive surgery; therefore a variety of methods and formulas, some of which required prerefractive surgery data, have been proposed to improve the accuracy of measurements and calculations...

Currently, infections following cataract surgery are not as effectively managed with antibiotic eye drops, which suffer from poor bioavailability of drug and low patient compliance. The ideal solution, which can help to overcome the issue of drug wastage and poor bioavailabilty, as well as the need for frequent applications (patient inconvenience), is a drug-eluting intraocular lens (IOL). We describe a novel approach to such a drug-eluting lens by using a peripheral IOL attachment as a drug depot to deliver antibiotics, Levofloxacin (LFX) or Moxifloxacin (MFX)...

PURPOSE: To compare measurements of axial length (AL), anterior chamber depth (ACD), keratometry (K), and the refractive predictability of the Aladdin and IOLMaster biometry devices in cataract surgery patients. METHODS: A retrospective observational study of eyes undergoing cataract surgery. Data were retrieved on AL, ACD, and K measurements obtained by the Aladdin and the IOLMaster. Furthermore, the postoperative refractive prediction errors were compared between the devices...

Recognizing imaging characteristics after ophthalmic surgery is necessary for radiologists to prevent misdiagnosis. We review typical appearances of intraorbital implanted devices and materials on CT and MRI with demonstration of the common surgical procedures. EX-PRESS glaucoma filtration devices appear as punctate areas of metal attenuation on CT and are typically placed at the corneoscleral junction. The imaging manifestations after cataract extraction are absence of the native lens of ovoid mass and the intraocular lens with high attenuation on CT and low signal intensity on MRI...

BACKGROUND: Ozurdex is a 700 mcg dexamethasone intravitreal implant, approved for the management of macular edema secondary to retinal vein occlusion, and other related pathoglogiesAnterior chamber dislocation of Ozurdex represents an uncommon complication of the intravitreal injection, which can be managed by repositioning the implant into the vitreous cavity. We describe the case of a successful repositioning of an Ozurdex implant by mobilization and subsequent balanced saline solution injection in the anterior chamber...

PURPOSE: To evaluate postoperative outcomes and visual performance in intermediate distance after implantation of a +1.5 diopters (D) addition, aspheric, rotational asymmetric multifocal intraocular lens (MIOL). METHODS: Patients underwent bilateral cataract surgery with implantation of an aspheric, asymmetric MIOL with +1.5 D near addition. A complete ophthalmological examination was performed preoperatively and 3 months postoperatively. The main outcome measures were monocular and binocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), distance corrected intermediate visual acuity (DCIVA), uncorrected near visual acuity (UNVA) and distance corrected keratometry, and manifest refraction...

PURPOSE: Secondary intraocular lens (IOL) placement in uveitic eyes is challenging. We describe a series of sclerally fixated IOLs using a transconjunctival sutureless (SIS) technique in eyes with history of uveitis. METHODS: This is an interventional, retrospective, consecutive case series. RESULTS: Five patients with a history of well-controlled uveitis were included. All underwent vitrectomy, with removal of residual lens fragments if necessary...

PURPOSE: To investigate agreement between the ocular biometry measurements provided by a newer optical biometer, the AL-Scan (Nidek Co, Ltd., Gamagori, Japan) and those provided by the IOLMaster 500 (Carl Zeiss Meditec, Jena Germany), which are both based on partial coherence interferometry. METHODS: Axial length, corneal power, and anterior chamber depth (corneal epithelium to lens) were measured in 86 eyes of 86 patients scheduled for cataract surgery using both biometers...
