Ocular Surface Disease Index (OSDI) The OSDI questionnaire was used to quantify the dry eye symptoms before surgery and 2 weeks, 1 month and 3 months postoperatively. In this questionnaire, patients were asked about dry eye symptoms that they had experienced during a 1-week recall period. Each answer was scored on a 4-point scale from zero (indicating no problems) to four (indicating a significant problem). Accordingly, we combined the responses to all of the questions to generate a composite OSDI score that ranged from 0 to 100, with higher OSDI scores indicating more severe symptoms. Statistical analysis We used SPSS version 20.0 (SPSS Inc., IBM, USA) in statistical analysis and results are expressed as mean ± standard deviation …show more content…
There were no statistically significant differences between the three groups in relation to age, preoperative spherical equivalent, central corneal thickness and keratometric readings (P>0.05) (Table 1). Table 1: Preoperative selected characteristics.

A one-way between subject ANOVA found insignificant differences between groups in age, preoperative and postoperative spherical equivalent (P>0.05). On the other hand, significant differences between groups were detected in the mean flap and cap thickness as it was 123.37±4.41μm in Lasik group, 105.03±2.49μm in the Femtolasik group and 105.89±2.21μm in the SMILE group
Were included 82 eyes of 49 patients, 32 (69%) females and 17 (31%) males. The mean patient age was 33 +/- 7.4 years (range: 21 to 48 years). Mean follow up was 4.8 years (range 9 to 1 year). The mean anterior chamber depth was 3.2mm (range 2.8 to 3.67mm). Were implanted 42 Artisan IOL and 40 Artiflex IOL with a mean power of -11.1D
Including all surgeries with suitable follow-up, DMEK patients had a preoperative mean BCVA ± SD of 0.64 ± 0.41 logMAR improving to 0.19 ± 0.16 logMAR at 5 years. A visual acuity of 20/40 or better was reached in 84% of eyes and of 20/25 or better in 48% (Table1).
Recognizing patient risk factors, and minimizing modifiable surgical risk factors are both important to avoid a debilitating sequela for the patient. Optimizing the management of patients with known ophthalmologic pathologies prior to undergoing any procedure that requires steep trendelenburg is also important in the preoperative assessment. Other approaches and modified positions should be considered prior to surgery. Patients with glaucoma should be made aware of the potential risk of blindness or loss of vision due to positioning prior to obtaining consent. A detailed preoperative and post-operative physical exam of the eye is imperative to be able to evaluate for corneal abrasions, exacerbated glaucoma, or any other new onset changes to the eye. As with any other case, comprehensive handoff reports are imperative to prevent further complications and to identify those patients who may be at risk upon emergence from general anesthesia and steep trendelenberg positioning. Anesthesiologists must make immediate clinical management decisions and obtain emergency ophthalmology consultation to reduce IOP and ultimately minimize permanent
The model also incorporated the cost of glaucoma surgery and vitrectomies, which were also reported in the FAME studies. The model considered AEs from intravitreal injections such as endophthalmitis and retinal detachments. The frequency of these events was assumed to be independent of treatment received, and incidence rates were calculated from pooled data from all patients enrolled in the FAME trials. The evaluation did not consider traumatic lens injury and vitreous hemorrhage because it could not be determined if these events were due to the treatment received or the underlying diabetes.
Clinical optometrists take on the task of routinely evaluating and dealing with patients on a daily basis while also attempting to maintain a healthy, successful business environment. The book Clinical Procedures for Ocular Evaluation describes how clinical optometrists maintain healthy relationships with patients and also detail different tests that are commonly implemented. These tests allow for doctors to determine a patient’s well-being and follow the necessary steps to improve the state of their eyes. Clinical Procedures for Ocular Examination is a viable tool that can be used to manage a patient’s complaints and general health history, and assess which phases of examination and problem-specific testing should be implemented.
painful and stressful disorder that can cause unrepairable sight problems, if left un-treated. How do we treat this disease? As the research shows there has not been a dramatic change in the eye drop treatment approach, to manage this disease. Dry eye is a common condition and often a chronic problem (particularly in older adults), in which a person does not have enough quality tears to lubricate and nourish the eye. Dry eye disease is a multifactorial disease in the ocular
Ancient Ophthamologist’s failed to understand many of the common eye conditions that are very prevalent in modern Ophthamotry. Many of the conditions of the eye that were
The study of the eye and its parts has led to much medical advancement in ophthalmology. Describe a condition/disease/disorder that affects the eye and how the structures in the eyes are affected by the condition/disease/disorder. What course of action is taken to relieve the problem and how are the structures and functions compensated for?
All patients were diagnosed with a stage 2, 3, or 4 idiopathic MH according to the Gass classification system(17) and underwent a comprehensive ophthalmologic examination before and 1, 3, and 6 months postoperatively, including measurement of the best-corrected VA (BCVA), binocular indirect ophthalmoscopy, and non-contact lens slit-lamp biomicroscopy.
We have found that a little knowledge on the history of LASIK, as well as a bit of information about the procedure itself, can go a long way towards assuaging any fear or trepidation a potential patient may have regarding the procedure. Towards that end, we thought this would be an excellent place to lay out a LASIK road map of sorts, and thereby help potential LASIK patients become more comfortable with the idea. The advances made in the development of LASIK procedures are slowly and inexorably making glasses and contact lenses obsolete, and a little nervousness shouldn’t stand in the way of anyone receiving these benefits. It is our hope that the following information on the history of LASIK, as well as the modern procedures and technologies available will help put an end to that nervousness. And really, if it can help eliminate the need for glasses or contacts, isn’t it all worth
Purpose: To analyze the influence of various surgical factors on the post-operative corneal refractive power and astigmatism after keratoplasty in eyes with corneal diseases.
Those with lower prescription strengths pre-surgery experienced fewer and less frequent side effects. Radial Keratotomy is now almost non-existent for these specific reasons as well as the advances in technology when it comes to laser vision correction.
An appropriate written informed consent was obtained from all patients before surgery in accordance with the Declaration of Helsinki. Patients with unrealistic expectations; anterior chamber depth less than 2.80 mm; IOP greater than 20 mm Hg; a history of ocular surgery or trauma, cataract, glaucoma, diabetes mellitus, other ocular or systemic autoimmune disease; less than 18 years old were excluded from the study.
This study included 59 eyes of 58 patients with mean age ± standard deviation (SD) of 54±11 years, and a range from 25 up to 70 years. The male to female ratio was nearly 2:1. Table 1 summarizes the preoperative visual acuity and IOP.
All patients were diagnosed with a stage 2, 3, or 4 idiopathic MH according to the Gass classification system(17) and underwent a comprehensive ophthalmologic examination before and 1, 3, and 6 months postoperatively, including measurement of the best-corrected VA (BCVA), binocular indirect ophthalmoscopy, and non-contact lens slit-lamp biomicroscopy.
