Oldest phacoemulsification cataract surgery for Analysis

When dilated fundus examination and found that changing the end of high myopia, retinal and choroidal atrophy in 2 eyes, 3 eyes with age-related macular degeneration, glaucoma,[link widoczny dla zalogowanych], optic atrophy in 3 eyes, proliferative diabetic retinopathy in 4 eyes, 2 eyes, vitreous opacity. L2.2 refraction 3 months after refractive surgery, 5 eyes myopic astigmatism, farsightedness, astigmatism 7, the degree 0.50D ~ 1.00D. 2.3 Intraoperative complications of posterior capsule rupture in 2 eyes, 1 day after different degrees of corneal edema in 7 eyes, giving subconjunctival injection of gentamicin, dexamethasone injection, with the Chinese smoked eyes,[link widoczny dla zalogowanych], most of the 1 week gone, no corneal endothelial decompensation. Cellulose anterior chamber exudation seven to give a Fu0.2mL 5 subconjunctival injection of 1 to 3 times,[link widoczny dla zalogowanych], all exudate absorption. 3 months to 1 year follow-up was no wound dehiscence, or lens shift, severe posterior capsular opacification 3, line YAG laser treatment. 3 Most of the discussion with the Oldest Old Cataract one or more systemic diseases. A conventional ECCE cataract surgery in elderly patients because surgery is difficult to tolerate a long time. In addition, as traditional cataract extraction, corneal incision about 10ITlm, not only recovered slowly wound, and whether continuous or interrupted suture, will be changed to varying degrees limbal anatomy of the original location, easy to have a greater postoperative astigmatism. In the delivery process because of the nuclear lens nucleus large, easy to damage the corneal endothelium, postoperative recovery was slow, visual acuity is not ideal. Our hospital from 1998 to 2003 of 124 110 cases of elderly cataract phacoemulsification and intraocular lens implantation, literacy rate of 100%, higher than extracapsular cataract extraction and intraocular lens implantation. Phacoemulsification and intraocular lens implantation with small incision, less damage, fewer complications, astigmatism is small, the advantages of faster visual recovery after surgery for elderly and frail elderly cataract patients. We believe that the very old cataract phacoemulsification and intraocular lens implantation, several aspects should be noted that (1) attention to general condition [1J: old age cataracts parts of their body is aging, most patients with chronic systemic diseases, so a certain preoperative to fully understand blood pressure, heart, blood glucose, the current illnesses and drug use, problems in time. Patients usually do not change as much as possible on medication, treatment and eating habits, do ideological work to eliminate fear of the patients the psychological tension, remained relatively calm, stable state of mind, to avoid the occurrence of cerebral vascular accident. Hypertensive patients before the general control of blood pressure 160/90mmHg, blood glucose control in general 8mmoL / L less oxygen as appropriate surgery, cardiac care, when necessary, the relevant sections of the MD intraoperative monitoring. (2) patients who need to have skilled surgical technique: old age cataracts mobility, can not be timely medical treatment, the lens nucleus to grade Ⅲ ~ Ⅳ more common, due to the nuclear hard, increasing the difficulty of phacoemulsification, posterior capsule rupture-prone, Intraoperative continuous, smooth curvilinear capsulorhexis of about 6mm in diameter [2J, adequate water separation, right of control ultrasonic energy, vacuum, flow rate, delicate posterior capsule polishing is key to successful operation. Authors believe that the hard and difficult the nuclear emulsion, should adopt a flexible surgical approach can be the lens nucleus of will be divided into a few pieces, and then asked out one by one,[link widoczny dla zalogowanych], to avoid long period of time caused by phacoemulsification intraocular tissue damage. On the other hand use the balance of fluid replacement viscoelastic agent and rinse residue, Suixiao the cortex, to prevent postoperative high intraocular pressure and other complications. The incidence of age-related macular degeneration with age and increased from 43 to 54 age group in the incidence rate of 8.5%, while the group aged 75 or older 【36.8l% incidence of diabetic proliferative retinopathy and high myopia retinopathy will increase the difficulty of operation, special attention should be to reduce the incidence of complications. In summary, clinical observations, for the oldest old cataract, fully understand the general condition before surgery, preoperative preparation to do, phacoemulsification and intraocular lens implantation is safe and feasible, after satisfactory.
