Background/objective To evaluate the visual performance of a purely refractive extended depth of focus (EDF) intraocular lens (IOL). Subjects/methods A prospective, multi-center, randomized, subject/evaluator-masked study. Subjects were bilaterally implanted with the EDF test (Model ZEN00V, N = 60) or an enhanced monofocal control (Model ICB00, N...

Purpose: To examine the 6-month outcomes of visual performance and positional stability of a capsule-fixated intraocular lens (IOL), FEMTIS Comfort MF15, extended depth-focus (EDOF) version, after cataract surgery performed using femtosecond laser-assisted cataract surgery capsulotomy. Setting: Vision Eye Institute, Sydney, Australia. Design:...

Objectives To determine the effect of hyperopic laser in situ keratomileusis (H-LASIK) on corneal integrity, by investigating relationships between proportionate corneal tissue ablated and refractive outcomes at 3 months. Methods 18 eyes of 18 subjects treated with H-LASIK by Technolas 217c Excimer Laser were included in the study. Orbscan II Topo...

Small incision lenticule extraction (SMILE) represents a recent addition to the refractive surgeon's range of procedures. Although there remains a number of similarities to existing techniques in terms of patient selection and treatment parameters, consideration is required to optimise patient outcomes and satisfaction. Here, we review the selectio...

Purpose: To describe a case of lacquer cracks developing after phakic intraocular lens implantation. Methods: Case report. Results: A 46-year-old woman diagnosed as having extreme myopia and corrected distance visual acuity of 20/40 presented with decreased vision and a central scotoma less than 24 hours following phakic intraocular lens impla...

Purpose: To investigate changes to corneal surface aberrations and vision between PresbyLASIK and LASIK for correction of presbyopia using the MEL 80 platform (Carl Zeiss Meditec, Jena, Germany). Methods: The retrospective data of 31 patients who underwent PresbyLASIK (the PresbyLASIK group) between January 2009 and November 2011 and 20 matched...

A 45-year-old woman presented to her ophthalmologist complaining of worsening uncorrected distance visual acuity following placement of an Implantable Collamer Lens phakic intraocular lens (pIOL) approximately 10 years earlier. Prior to the pIOL surgery, contact ultrasound axial length (AL) measurements of 28.28 mm in the right eye and 27.90 mm in...

The surgical management of aphakia is a rewarding task providing greatly improved visual function and patient satisfaction. Of the many options available, retropupillary placement of an iris claw lens offers several advantages. The relative place of this approach is explored, and the surgical technique described.

To report a case of traumatic flap dehiscence and Enterobacter keratitis 34 months after LASIK. A 36-year-old man sustained a flap dehiscence following traumatic right eye gouging by a seagull claw. He presented the following day with uncorrected visual acuity (UCVA) in the affected eye of 3/200 and organic foreign body deposits underneath the flap...

A bstract Ocular involvement is a common complication of HIV infection. Since the late 1990s, widespread use of highly active antiretroviral therapy (HAART) has altered the spectrum, and reduced the incidence of ocular involvement in developed countries. The incidence of the most common ocular opportunistic infection, cytomegalovirus retinitis, has...

Penetrating keratoplasty in the presence of a perforated cornea is a relatively common and difficult surgical problem. In the worst scenario, there may be extrusion of ocular contents during trephination. Two cases of perforated corneas are presented in which a new technique was used to close the perforation and normalize intraocular pressure. This...

To evaluate the safety and efficacy of laser ablation on the flap as a treatment for a refractive error. Laser Sight Centres, Sydney, Australia. In this noncomparative case series, 142 treatments were performed in 98 patients using cornea-sparing laser in situ keratomileusis (LASIK) with ablation of the corneal flap and, in some cases, also the str...

To review the clinical features and possible aetiology of all cases of Möbius' syndrome presented at the Royal Alexandra Hospital for Children in Sydney, Australia, from 1963 through 1995. All charts of patients suffering from Möbius' syndrome were reviewed, and each patient was thoroughly assessed by a geneticist and a pediatric ophthalmologist. P...

Methods: All charts of patients suffering from Möbius' syndrome were reviewed, and each patient was thoroughly assessed by a geneticist and a pediatrie...

To determine the results and complications from the use of ganciclovir implants to treat patients with HIV infection and cytomegalovirus (CMV) retinitis. The present study was a retrospective review of 87 consecutive ganciclovir implant surgeries performed in 60 patients over a 3 year period. Based on the results of the present study, ganciclovir i...

Cataract is the leading cause of blindness worldwide, accounting for half of the world's blind population. It is the commonest cause of mild to severe visual impairment in Australia. Currently the sole treatment is surgical extraction of the involved lens. This article discusses how cataract presents and outlines the preoperative testing of the pat...

The technique of endocapsular cataract extraction and intraocular lens implantation surgery provides optimal surgical conditions and more reliable intraocular lens positioning in the capsular bag. Several capsulectomy techniques are in use to remove anterior capsule from the central zone. The Koch endocapsular punch provides a new technique for cre...
