PURPOSE: To investigate the potential impact of cone eccentricity on visual outcomes after Keraring (Mediphacos, Belo Horizonte, Brazil) implantation for keratoconus. METHODS: Nineteen eyes from 19 patients with keratoconus who underwent femtosecond laser-assisted Keraring implantation for keratoconus were included in this retrospective study. Uncorrected visual acuity (UDVA), corrected visual acuity (CDVA), keratometric readings, central corneal thickness, maximum keratometric distance from corneal apex (DKmax), corneal thinnest point from corneal apex (DTh), and coma were evaluated preoperatively and 6 months after the Keraring implantation...

BACKGROUND: Intracorneal ring segment implantation is an effective and safe method of visual improvement in patients with keratoconus. The aim of our study was to evaluate the long-term clinical outcomes after Keraring implantation for keratoconus in patients older than 40 years. METHODS: Eleven eyes from 11 patients with keratoconus who underwent femtosecond laser-assisted Keraring implantation for keratoconus were included in this retrospective study. The uncorrected visual acuity (UCVA), corrected visual acuity, keratometric readings, central corneal thickness and thinnest corneal pachymetry were evaluated preoperatively and 6 months after the Keraring implantation...

AIM: To assess the effect of cyclosporine-A (CsA) 0.05% ophthalmic emulsion on corneal sensation and ocular surface problems following cataract surgery. DESIGN: Prospective, randomized, double masked clinical trial. METHODS: Consecutive case series of patients attending for bilateral cataract surgery. Subject's eyes were randomized to receive either topical CsA or carboxymethylcellulose 0.5% (CMC) eye drops twice daily for one month following routine cataract surgery...

Purpose. To compare the surgical outcomes of staged and combined phacoemulsification with intraocular lens implant (phaco+IOL) and Descemet stripping automated endothelial keratoplasty (DSAEK) in patients with Fuchs' endothelial dystrophy and cataract. Setting. Corneoplastic Unit and Eye Bank, Queen Victoria Hospital, East Grinstead, UK. Methods. Retrospective study of patients who had combined phaco+IOL and DSAEK (group 1) or phaco+IOL followed within 2 months by DSAEK (group 2). Patients who had previous eye surgery or any other ocular comorbidities were excluded...

BACKGROUND: Keratoconus is a condition of the eye that affects approximately 1 in 2000 people. The disease leads to a gradual increase in corneal curvature and decrease in visual acuity with consequent impact on quality of life. Collagen cross-linking (CXL) with ultraviolet A (UVA) light and riboflavin (vitamin B2) is a relatively new treatment that has been reported to slow or halt the progression of the disease in its early stages. OBJECTIVES: The objective of this review was to assess whether there is evidence that CXL is an effective and safe treatment for halting the progression of keratoconus compared to no treatment...

BACKGROUND: The syndrome of childhood blepharokeratoconjunctivitis (BKC) is frequently underestimated. While prevalent and aggressive among Indo-Pakistani/Middle-Eastern populations, we observe a recalcitrant destructive phenotype in white children/adolescents that persists into early adulthood and may require systemic immunosuppression. METHODS: A cohort of 10 white patients (20 eyes), median age 15.2 (range 6-27) years were identified among 62 patients with BKC attending a tertiary referral centre...

PURPOSE: To revisit the clinical presentations of Salzmann's nodular corneal degeneration (SNCD) and to identify risk factors, occurrence and prognosis, and in particular to assess the role of previous contact lens wear as an aetiological factor. METHODS: Retrospective case note review of all cases of Salzmann's nodular degeneration over the last twenty years. We analysed epidemiological features, characteristics of lesions, risk factors and final outcomes. RESULTS: Thirty eyes (19 patients) were identified with SCND...

An 84-year-old white female with nonprogressive conjunctival scarring developed infectious crystalline keratopathy (ICK) recalcitrant to topical therapy. After determination of the causative organism's antibiotic sensitivities, superficial keratectomy was performed with intrastromal corneal infiltration of cefuroxime into the affected cornea. Postoperatively, the ICK resolved completely, leading to an improvement in visual acuity and a reduction in ocular irritation. This case highlights the importance of a surgical approach in ICK and also demonstrates the possible benefit of a novel use of intracorneal antibiotics as an adjunct...

PURPOSES: To describe the technique and evaluate the outcomes of patients who had deep anterior lamellar keratoplasty (DALK) for ectasia within or outside the graft-host interface in a previous penetrating keratoplasty (PK). DESIGN: Retrospective review of interventional case series. PATIENTS: Seven eyes that underwent DALK for corneal ectasia after previous PK. INTERVENTION: DALK encompassing the area of ectasia and the previous PK...

PURPOSE: To evaluate childhood filtration surgery when using releasable sutures, antimetabolites, and bleb-needling with 5-fluorouracil (5FU). METHODS: Retrospective case note review of 30 patients (38 eyes) with childhood glaucoma presenting between 1999 and 2004 to a tertiary pediatric ophthalmology center. Either trabeculectomy or combined trabeculotomy-trabeculectomy using antimetabolites, releasable sutures, and bleb modification was performed. Successful outcomes for survival analysis were measured intraocular pressures < or =21 mmHg, with two or less topical medications...

PURPOSE: To describe the authors' 5-year experience of the 2-incision push-pull (TIPP) technique for pediatric anterior and posterior capsulorrhexis formation. DESIGN: Retrospective descriptive study over a 5-year period. PARTICIPANTS: A total of 84 eyes of 63 patients who had undergone cataract surgery in 1 center. METHODS: Retrospective review of all consecutive patients who underwent pediatric cataract extraction with planned intraocular lens implantation and TIPP rhexis between January, 1999, and August, 2004...

A 6-year-old boy with Schwartz-Jampel syndrome and severe myotonia-induced blepharospasm and ptosis did not respond to botulinum toxin A injections in the orbicularis muscle. The clinical diagnosis was further supported by electromyography. Surgical management using a combination of techniques in one operation produced a satisfactory result for both function and appearance. Muscle biopsy was also done during surgery.
