1. Effects on ocular discomfort and tear film dynamics of suturing 23-gauge pars plana vitrectomies
RESUMO Objetivo: Avaliar os efeitos da sutura da vitrectomia via pars plana de 23-gauge sobre o desconforto ocular e a dinâmica do filme lacrimal. Métodos: Esta revisão retrospectiva de prontuários envolveu dados de 50 casos em 50 pacientes submetidos à vitrectomia via pars plana de 23-gauge, de janeiro a novembro de 2016. Dividimos os olhos em dois g

2. THE USE OF CYANOACRYLATE ADHESIVE FOR FIXATION OF CORNEAL AUTO E ALOIMPLANTS PRESERVED IN 98% GLYCERIN IN THE PENETRATING KERATOPLASTY IN RABBITS / USO DE ADESIVO DE CIANOACRILATO PARA A FIXAÇÃO DE BOTÃO CORNEAL AUTÓGENO OU ALÓGENO CONSERVADO EM GLICERINA A 98% NA CERATOPLASTIA PENETRANTE EM COELHOS.
The present research had the objective to evaluate the use of an n-butil cyanoacrylate in the fixation and maintenance of corneal autografts and aloimplants in the penetrating keratoplasty. There were used eight adult rabbits divided in two groups: the group I adhesive (GI 4 animals) and group II suture (GII 4 animals). In the GI, performed in the left eye,

3. Keratomery system of the support to corneal sutures / Sistema ceratométrico de apoio a suturas na córnea
Um sistema para auxílio à cirurgias oftálmicas foi desenvolvido com o objetivo de se minimizar o astigmatismo induzido devido ao formato irregular da córnea pelo ato de sutura. O sistema projeta 48 pontos de luz no filme lacrimal da córnea, provenientes de LEDs, dispostos num diâmetro precisamente circular. O deslocamento, a dimensão e a deformação

4. Astigmatism in cataract surgery.
We report on our investigation into astigmatism in 40 eyes following a corneal cataract incision closed with a continuous 10/0 nylon monofilament suture (Ethilon). Immediately after surgery there was astigmatism caused by the nylon suture (suture-induced astigmatism), its severity depending on the tightness of the suture. It ranged from 1 to 10-5 dioptres, t

5. Scanning electron microscopic study of monofilament suture knots.
AIMS/BACKGROUND: Interrupted corneal sutures are used routinely by many cataract and corneal surgeons. A slim compact knot facilitates burial and allows atraumatic suture removal, with decreased risk of wound dehiscence. The size and morphology of knots tied in different configurations were investigated. METHODS: 10-0 nylon suture material was used to tie kn

7. Should nylon corneal sutures be routinely removed?
Three groups of patients who had undergone cataract extraction through a corneal incision closed with 10/0 nylon sutures one, two, and three years previously were recalled to determine the incidence of suture related complications. Broken corneal sutures were found in 87.5% of patients after two years and 90% after three years and were causing symptoms in ov

8. Control of postoperative astigmatism.
Thirty-six eyes with excessive astigmatism following cataract extraction via a corneal section were subjected to suture adjustment. This was performed six to eight weeks postoperatively under topical anaesthesia. The cases were selected from a large volume of corneal section cases because they had over 3.0 dioptres astigmatism. We reduced astigmatism signifi

9. Stabilisation of refraction following extracapsular cataract extraction.
Regular serial refraction was used to determine the rate of stabilisation of refraction following routine extracapsular cataract surgery in 85 eyes. Patients were divided into four groups depending on wound closure technique: limbal section closed by interrupted 8-0 virgin silk, 9-0 polydioxanone or 10-0 nylon sutures, and corneal section closed by continuou

10. Photokeratoscopy in fitting contact lens after penetrating keratoplasty.
The formula based on keratometric readings which is generally used is unsatisfactory for fitting contact lenses after penetrating keratoplasty, possibly owing to lack of information on the peripheral corneal toricity. In these studies a photokeratoscope was used to examine the entire graft topography. In all cases the corneal configuration became more normal

11. Scanning electron microscopic study of Dacron degradation by ocular tissue extracts.
A scanning electron microscopic study showed that the surface of Dacron thread became significantly roughened after treatment with bovine iris-ciliary body extracts. The Dacron-degrading factor in the extract was nondialysable, heat-labile, and active at an acidic pH, suggesting that lysosomal enzymes may be a factor in this phenomenon. Bovine extracts from
