Control of astigmatism after surgery and trauma.
Since the introduction of microsurgical accuracy in the closure of corneal wounds, there have been fewer complications due to imperfect wound closure. As a result the eye is much safer after intraocular surgery or trauma. There may, however, be an undesirable and irregular refractive error. Much thought has been given to the prevention of this by attention to other details during closure of wou...
متن کاملControl of astigmatism after surgery and trauma: a new technique.
Five patients were subjected to a new technique designed to correct high astigmatism not responding to suture removal or adjustment. The method is described and its use illustrated in five case histories. Four of the five cases were successfully treated. The reasons for the one failure are discussed. All procedures were uncomplicated. The technique is simple, safe, and reversible.
متن کاملControl of astigmatism in cataract surgery.
A study is reported on cataract surgery, with intraocular lens implant, with measurement of the preoperative astigmatism and of the postoperative astigmatism over 28 weeks. Nine interrupted 10/0 nylon sutures are used to close a limbal section. Preoperative astigmatism is compensated for in the method of suturing by the placement of additional sutures. Postoperatively sutures are cut in line wi...
متن کاملInfluence of posterior corneal astigmatism on postoperative refractive astigmatism in pseudophakic eyes after cataract surgery
BACKGROUND To examine the influence of posterior corneal astigmatism on postoperative refractive astigmatism in pseudophakic eyes after cataract surgery. METHODS The study enrolled 64 pseudophakic eyes of 50 patients (71.8 ± 9.9 years old, mean ± standard deviation) who had undergone phacoemulsification with non-toric IOL implantation. Refractive astigmatism was measured using an auto ref-ker...
متن کاملAstigmatism following cataract surgery.
The changes in corneal curvature were determined at regular intervals over a one-year period following intracapsular cataract extraction by microsurgical techniques. During the first postoperative month photokeratometric measurements showed rapid changes in astigmatism associated with large changes in the direction of the axis. Thereafter astigmatism against-the-rule predominated. Data from the...
