Comparison of complications of intrascleral fixation according to the extent of vitrectomy.

Background: Intraocular lens (IOL) fixation is performed after intraoperative anterior or total vitrectomy. This study aimed to compare the intraoperative and postoperative complications of these two techniques.

Methods: This retrospective study included 235 eyes that underwent intrascleral fixation surgery at our hospital between July 2014 and January 2021.

Phacoemulsification without hydrodissection: Semi-crater and split technique.

Unlabelled: We present a semi-crater sculpting and split technique for simple nucleus removal and hydrodissection-free phacoemulsification. In this technique, the crater sculpting is done in half the nucleus only and emulsified before nucleus rotation. The remaining half of the nucleus is freed from the capsule and then rotated to the opposite side of the phaco tip and emulsified.

Modified capsule expander implantation to reposition and fixate the capsular bag in eyes with subluxated cataractous lenses and phacodonesis: intermediate-term results.

Purpose: To report the intermediate-term results of capsule stabilization for scleral fixation with implantation of the Yaguchi hook, a modified capsule expander stabilization hook.

Setting: Department of Ophthalmology, School of Medicine, University of Showa, Fujigaoka Rehabilitation Hospital, Yokohama, Japan.

Design: Retrospective case series.

Effect of decentration on the optical performance in multifocal intraocular lenses.

Aims: To evaluate the influence of decentration on optical performance in multifocal intraocular lenses (IOLs) using eye models.

Methods: This study evaluated 4 types of multifocal IOLs (ReSTOR SA60D3, Alcon; TECNIS Multifocal ZM900, AMO; ReZoom, AMO; SFX-MV1, Hoya). The evaluations were based on measurements of the near and far modulation transfer function (MTF) and visualized actual near images (newspaper) using eye models with the IOL horizontally displaced 0, 0.

Cytotoxicity of topical medications used for infection and inflammation control after cataract surgery in cultured corneal endothelial cells.

Postoperative vision-threatening corneal edema sometimes occurs after eye surgery, and corneal endothelial damage may be caused or exacerbated by drug toxicity. A range of commercially available antibiotic and anti-inflammatory ophthalmic solutions used postoperatively, namely levofloxacin, moxifloxacin, gatifloxacin, cefmenoxime, diclofenac, bromfenac, pranoprofen, betamethasone, and fluoromethorone, were assessed by using human corneal endothelial cells (HCECs). Propylparaoxybenzoate and methylparaoxybenzoate were also examined.

Cytotoxicity of five fluoroquinolone and two nonsteroidal anti-inflammatory benzalkonium chloride-free ophthalmic solutions in four corneoconjunctival cell lines.

Purpose: Epithelial disorders after eye surgery can result in visual deterioration and patient discomfort. Such disorders may be caused by drug toxicity. In the present study, we evaluated the toxicity of ophthalmic solutions, with or without benzalkonium chloride (BAK) as the preservative, used for postoperative care.

[Evaluation of post intraocular lens implantation detrition of clear corneal incisions using an injector system in porcine eyes].

Purpose: To evaluate the detrition of clear corneal incisions (CCIs) after intraocular lens (IOL) implantation using an injector system in porcine eyes.

Methods: Group A: after CCIs were performed with 1.8, 2.

[Retinopathy during interferon treatment in combination with ribavirin for chronic hepatitis C].

Purpose: To observe the retinopathy of the patients who received interferon/ribavirin for treatment of chronic hepatitis C.

Methods: We observed 6 patients(5 males and 1 female) who received interferon/ribavirin for treatment of chronic hepatitis C. Visual acuity tests and detailed fundus examinations were performed monthly during 6 months of interferon/ribavirin therapy.
