Introduction: We describe a novel surgical technique of slit-beam retro-illumination assisted phacoemulsification for cataract with coexisting corneal opacity. Cases: We present two cases with cataract and coexisting opacity, who underwent slitbeam retro-illumination assisted phacoemulsification and further application of same process in 12 patients. Conclusion: This technique is safe and provides excellent visualization during cataract surgery in patients with corneal opacities.

Post Operative Complications

Background: Despite significant advances in canine cataract surgery over the years, many post-operative complications persist and reduces the success rate of phacoemulsification procedure. The aim of current study was to evaluate post-operative complications encountered till 90 days after bimanual phacoemulsification with implantation of different acrylic Intraocular Lenses.Methods: The study was conducted on 24 canine eyes. All the clinical cases were subjected to detailed ocular, ultrasonography and neuro-ophthalmic tests for ascertaining cataract and associated neuro-ophthalmic pathology. Dogs were divided in four groups with 6 eyes in each group and subjected to phacoemulsification procedure for removal of cataractous lens and implanted with square edge or round edge hydrophilic or hydrophobicintra ocular lenses.Result: Statistically non-significant (p£0.05) variations were found for all the post- operative complications among the groups. Within the groups initially higher values were recorded and on subsequent days a declining trend of varying degrees were observed. The corneal opacity was a major postoperative complication leading to failure to achieve vision with other coinciding neuro-ophthalmic conditions.

Introduction: Corneal disease, especially infective keratitis, is one of the major causes of visual impairment and blindness in developing countries. Objective: To find out the current indications for keratoplasty, how these indications have changed over time as well as how they are different from those in other parts of the world. Materials and methods: A retrospective study of a case series of 645 keratoplasty surgeries (589 patients) was conducted at the Tilganga Institute of Ophthalmology from January 2005 to December 2010. Outcome measures: The cases were evaluated in terms of demographic parameters, preoperative diagnosis and the type of surgery performed. Results: The most common indication for surgery was active infectious keratitis (264 eyes, 40.9 %), followed by corneal opacity (173 eyes, 26.8 %), regraft (73 eyes, 11.2 %), bullous keratopathy (58 eyes, 9.0 %), keratoconus (45 eyes, 7.0 %) and corneal dystrophy (11 eyes, 1.7 %). The mean recipient age was 41.7 ± 19.9 years with over a half of the patients between 15 to 49 years of age. More men (64.1 %) underwent keratoplasty than women (35.8 %). 59.8 % of the eyes with infectious keratitis had a perforated corneal ulcer. 49.7 % of corneal opacities were due to previous infectious keratitis. 72 % of regrafts were for endothelial failure of various causes. In older patients (> 50 years), bullous keratopathy was an important indication, after infectious keratitis. Keratoconus and corneal scar were major causes of keratoplasty in children of 14 years or less. Four percent of the patients had keratoplasty in both the eyes. 17.1 % of the patients who had one eye operated on had a blind fellow eye with a vision of less than 3/60. Conclusion: Currently, keratitis, either active or healed, is the major indication for keratoplasty, suggesting that improved primary eye health care is necessary to decrease the prevalence of corneal blindness.

Topic: Empress Eugénie (1826–1920), the widow of Emperor Napoléon III of France, developed mature cataracts late in life. In 1920, at age 94, she underwent surgery to one eye by Ignacio Barraquer (1884–1965), a member of the famous dynasty of ophthalmologists originally from Barcelona, Spain. Clinical relevance: Barraquer used his new instrument which employed a vacuum cup to hold the lens for intracapsular extraction. Methods: Research of historical documents. Results: The surgery was a success; the Empress was pleased that she could read again although she did not have long to live. She was his first famous cataract patient and his fame spread internationally. Barraquer spoke at the International Congress of Ophthalmology held in Washington, DC, in 1922 and demonstrated his technique on patients in Washington, DC, New York, Boston, Philadelphia and Richmond, VA. Conclusion: Barraquer's surgery on Éugenie, who was the most powerful woman in Europe during her husband's reign, influenced the course of development of cataract surgical technique.

ObjectiveTo characterise types of corneal diseases and resulting visual impairment (VI) in a rural North Indian population.DesignCross-sectional, population-based study.MethodsThe Corneal Opacity Rural Epidemiological study included 12 899 participants from 25 random clusters of rural Gurgaon, Haryana, India to determine the prevalence of the corneal disease in the general population. Sociodemographic details, presence and type of corneal morbidity, laterality, VI (presenting visual acuity (PVA) <6/18 in the better eye) and characteristics of corneal opacities were noted.ResultsOverall, 12 113 participants of all ages underwent detailed ophthalmic examination and prevalence of corneal opacity was found to be 3.7% (n=452) with bilateral involvement in 140 participants (31%) during the house-to-house visits. Of the total 571 eyes of 435 patients presenting with corneal opacity at the central clinic, PVA was <3/60 in 166 (29.1%), 3/60 to <6/60 in 14 (2.5%), 6/60 to <6/18 in 164 (28.7%), 6/18 to ≤6/12 in 85 (14.9%) and 6/9 to 6/6 in 142 eyes (24.9%), respectively. Further, there were a total of 115 eyes (20.1%) with nebular corneal opacity, 263 (46.1%) with macular, 162 (28.4%) with leucomatous and 31 (5.4%) with an adherent leucoma. The odds of having VI due to corneal disease were greater for the illiterate (OR:4.26; 95% CI: 2.88 to 6.31; p<0.001) and elderly (OR:11.05; 95% CI: 7.76 to 15.74; p<0.001).ConclusionThe data from this study give an insight into the characteristics of various corneal pathologies and resulting VI in the general population. This is a pioneer study involving all age groups on the burden of VI due to corneal diseases.

Purpose. To evaluate Fourier-domain optical coherence tomography (FD-OCT) as an adjunct to traditional slit lamp examination of donor corneas with suspected Anterior Stromal Opacities.Methods. Seven corneas suspected of having anterior stromal opacities by slit lamp examination were evaluated with FD-OCT. Each cornea was evaluated to confirm the presence of opacity and, if present, the depth of opacity was measured.Results. The opacity depth ranged from 82 μm to 624 μm. The initial slit lamp impressions of five of the seven corneas were confirmed by OCT. In two corneas, the OCT findings were different from the initial slit lamp impressions. Slit lamp examination of the first cornea gave the impression of anterior stromal scarring, but OCT showed that the opacity was limited to the epithelium. Slit lamp examination of the second cornea suggested opacity limited to the epithelium, but OCT identified significant sub-Bowman's scarring. In all cases, the Eye Bank Technicians reported that the location and depth of corneal opacity were more sharply defined by OCT than by slit lamp.Conclusion. The high resolution of OCT makes it easier to determine the location of corneal opacities compared to slit lamp examinations. This enhanced visualization can improve decisions regarding transplant suitability of donor corneas.
