Impact of preoperative testing on ophthalmologic and systemic outcomes in cataract surgery

PURPOSE. To evaluate the incidence of ophthalmologic and systemic complications in patients who undergo cataract surgery without preoperative tests compared to subjects undergoing cataract surgery preceded by preoperative tests. METHODS. The randomized controlled study included 1276 consecutive patients admitted to the Institute of Ophthalmology of the University of Modena and Reggio Emilia for cataract surgery. The patients were randomly divided into two groups: 638 were assigned not to undergo preoperative evaluation based on routine medical tests and electrocardiograms; the other 638 underwent preoperative evaluation based on said tests. Ophthalmologic and systemic complications were assessed intraoperatively and 1 month after surgery. RESULTS. Eleven intraoperative complications occurred in the group without preoperative tests and eight in the group with preoperative tests; at 1 month six complications were recorded in the group without tests and five in the group with tests. Systemic adverse events occurred intra operatively in four patients, whereas no systemic adverse event was recorded at 1 month in either group. No statistically significant differences were observed between the two groups. CONCLUSIONS. The findings of this study have broad applicability, because the sample is representative of the population existing in numerous social and healthcare settings; they are of value for administrative purposes, because they may be taken as reference in resource allocation plans; and they have medicolegal implications, as the resulting conduct of healthcare providers is supported by a rigorous scientific study

Morphological Aspect of LASEK. Lasek & Asa History Technique Long-term Results.

The quality of the results of a photoablative refractive surgery procedure is determined by a number of factors. From amongst these, two anatomo-physiological factors play a critical role in influencing firstly the action of the laser beam and secondly, the repair reaction started up by the stromal- epithelial complex, as a response to the wound. These factors reside in the degree of smoothness of the surface on which the laser is applied and in the protective system of the post-photoablation residual stroma. The connecting link between these two aspects is the method used for preparing the stromal bed to be treated, which represents the first stage of the keratorefractive operation with the laser. There are two basic procedures for preparing the stromal bed: the creation of an epithelialstromal flap (LASIK technique) and the corneal disepithelialization (PRK technique). The LASEK technique was proposed with the goal of combining the advantages of both methods and of eliminating the possible risks associated with them at the same time. It provides for the removal of the epithelium, as an integral epithelial flap, to be repositioned on the treated stroma at the end of the laser treatment. With the aim of ascertaining the efficacy of the LASEK method, a large number of pre-clinical and clinical studies have been conducted to evaluate the two critical factors cited at the beginning, i.e. the surface on which the laser is applied and the consequent repair reaction of the stromal-epithelial complex

Bottle-cork injury to the eye: a review of 13 cases

PURPOSE. To analyze the anatomic and functional consequences of wine-cork injury to the eye in relation to the patient's age and them type of cork and wine. METHODS. We retrospectively studied 13 patients, six Women and seven men, presenting to our department with-bottle-cork injury to the eye between January 1999 and June 2001. RESULTS. All patients presented with closed-globe injury according to Kuhn et al's classification. All the cases were injured by bottle corks from sparkling wine: white in ten cases and red in three. Mean visual acuity at admission was 201100 (range, hand motion to 20120). The most frequent early injury was anterior chamber hyphema (84.6%), followed by corneal injury (62.2%), ocular hypertension (46.1%), lens subluxation (30.8%), traumatic cataract (23.1%), and post-traumatic retinal edema (23.1%). Mean final visual acuity was 20125; the follow-up ranged from 3 to 29 months, averaging 16.1 months. Late complications were as follows: pupil motility anomalies (38.5%), traumatic cataract (30.8%), iridodialysis (15.4%), traumatic optic neuropathy (7.7%), post-traumatic glaucoma (7.7%), and traumatic maculopathy (15.4%). Surgical treatment was necessary in two cases (15.4%). CONCLUSIONS. Bottle-cork eye injuries account for 10.8% of post-traumatic hospital admissions to our department. Most of them are due to sparkling white wine served at room temperature. There is no correlation between ocular injury and the eye-bottle distance or the type of cork
