Advantages And Disadvantages Of Keratoplasty

After the surgery we observed that 79 eyes gain 4 or more lines of vision, 20/40 or better was achieved in 76 eyes (92.68%) after the follow up period.

the globe. However, this code makes no mention of corneal disease, scarring, or any condition requiring treatment that might be used to improve vision that is deficient because of corneal disease. Health New England’s Clinical Review Criteria includes a list of conditions of the eye for which scleral contact lenses would be approved for coverage, as follows:

During the assessment of sensory perception, it was noted that after having Lasik surgery approximately fifteen years ago, she has had no problems with vision and has her vision checked

While it is an unavoidable fact that you will require some time to heal following this procedure, the worst of the symptoms will only last for the first couple of days after the surgery. During this time, you may find that your eyes are almost completely swollen shut. This will be followed by a general soreness and bruises that may last for up to a week, and your doctor may recommend using ice packs to reduce the swelling as well prescribing pain medications to reduce your physical discomfort. You will also need to make several follow-up visits to ensure that your eyelid is healing

During my high school career, I became fascinated with the workings and functions of our eyes while attending an internship at an ophthalmologist's office. Through my time there I was fortunate to be able to shadow and assist both the ophthalmologists and optometrists. While taking corneal topographies of patients' eyes before they were examined, my interest continued to grow and that interest blossomed into a desire to pursue this as a career when I had the opportunity to witness my first eye surgery. Though the pterygiectomy was a simple procedure, I was inspired by the fact that it could allow the patient to see better, changing their life.

Glaucoma occurs when there is an increase of intraocular pressure or IOP; IOP is the pressure of the fluid within the eye that builds up behind the eye (Ignatavicius & Workman, 2013). If the retinal ganglion cells degenerate, the visual field will decrease as well as the optic nerve will atrophy causing a distinctive clinical appearance (Gemenetzi, Yang, & Lotery, 2012). There are several types of glaucoma but the main two types of glaucoma; open-angle and

For each patient, the automated visual field tests were obtained by Humphrey Field Analyzer and optic disc images by Topcon fundus camera. Horizontal and vertical cup-to-disc ratios were calculated by a manual, planimetric technique. Mean deviation (MD) and pattern standard deviations (PSD) were documented.

• Looking through the pupil into the back of the eye to examine the retina (fundoscopic exam) with a light (ophthalmoscope).

Post-cataract endophthalmitis is a rare but serious complication.1 Recent studies show a rate of postoperative endophthalmitis after cataract surgery of 0.04% to 0.29%.2-4 However, it remains the most important concern for surgeons, because it can have devastating consequences on vision.5 It is recently reported that 9% of patients with endophthalmitis have a poor ocular prognosis (visual acuity <20/100).6

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).

Afer 1 month 48% (12 o 25 eyes) gained 1 line or more o BSCVA, afer 1 year 64% (16 o 25 eyes) gained 1 line or more o BSCVA, afer 2 year 72% (18 o 25 eyes) gained 1 line or more

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

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.

It can only be assume that these complications were also associated with past couching procedure. This method however has proven to have a very low success rate , one would wonder why people went with through the operation , but it makes sense that the patients had very little alternative , as it was either blindness or attempt to see clearly , another factor that played a role was the oculist were highly respectable people in society. After the 19th century couching fell out of fashion even if it’s still being practised in some areas of Africa to this day , for example in Nigeria. And the tradition healers practise this method they have learned from their forefathers, items such a thorns or needles are used and complications associated with the couching are such as secondary glaucoma, hyphaema and optic atrophy. Part of reason it is still practised is hat professional surgery is highly costly so patients go for alternatives.

This includes a decrease in your vision, an increase in the after-surgery pain, increased redness, increased swelling and discharge coming from your eye. Further signs to be aware of includes more floating or new floaters appearing to impair your vision.
