Cataract Service

Cataract Treatment at the Department of Ophthalmology, Kinki University Faculty of Medicine

Cataract occurs when the lens becomes opaque with various causes, which leads to visual loss. Age-related cataract cases number the largest among the various types of cataract. Atopic dermatitis or diabetes can also cause cataract, which is making a big issue.

At the Department of Ophthalmology, we first prescribe eye drop to delay the progression of the cataract and follow up when the degree of visual loss of the patient is not so severe as to make the daily life difficult. However, the medication is not capable of deterring the progression of cataract and the patient needs to undergo cataract surgery when his/her visual loss is remarkable or causes difficulty in the daily life. For cataract surgery at our clinic, three days are necessary including one day each before and after the operation. When the patient needs the surgery on both eyes, the surgery is given separately for each eye. After the first operation of one eye, prognosis is observed for one week when most cases of postoperative infection take place. If the prognosis is fine, the other eye is operated. In most cases, the surgery is operated with the phacoemulcification method under local anesthesia, in which the opaque lens is fragmented with the ultrasonic wave and aspirated, and the intraocular lens is implanted. When the cataract is in more advanced stage where the nucleus is hardened, there is ECCE (extracapsular cataract extraction) to extract the whole lens, and the intraocular lens is implanted. In the year 2008, we experienced 1023 cases of cataract surgery and we are also emphasizing on the treatment of cataract complicated with atopic dermatitis. There are cases of aftercataract in which visual loss takes place in the operated eye or its vision becomes blurry one or two years after the surgery. In such cases, we use a laser for a very short time to remove the opacification of the lens as outpatient surgery to improve the visual acuity.
