[The value of inferior trabeculectomy in combined cataract-glaucoma surgery. Apropos of 54 cases].

In 54 consecutive cases of glaucoma triple procedure, a trabeculectomy was systematically performed at six o'clock. By separating the order and the locations of the incisions as well as their placement in limbo-corneal sites, haemorrhages are minimized. A watertight, controlled running suture avoids post-operative flat anterior chamber, and permits rapid tonometric normalisation. The results of these first cases are: a mean post-operative ocular pressure (O.P.): 15.1 mmHg, mean drop of O.P.: 36%; tonometric normalisation and visual-functional improvement above 90%.

[Value of qualitative keratometry for the correction of postoperative astigmatism].

The use of a per operative qualitative Keratometer is of interest in prevention of astigmatism in cataract extraction. Our study, which included two groups of forty patients each, demonstrated that the Karickhoff Keratometer can markedly decrease the degree of immediate post-operative astigmatism = gain of 2.38 delta in comparison with the control group and astigmatism less than or equal to 2 in 35% of the cases.

[Ocular implantation and exfoliative syndrome].

Operative difficulties and post operative complications after posterior chamber lens implantation are described in 27 eyes with exfoliation syndrome, 8 simple exfoliation syndromes and 19 capsular glaucoma. 14 eyes were operated on by extracapsular extraction and posterior chamber lens implantation in the capsular bag; 13 eyes had extracapsular cataract implantation combined with trabeculectomy. Operative difficulties were due to bad mydriasis and zonular laxity. There was no zonular dialysis. Post-operative visual acuity was between 20/40 and 20/20 in 70% of the cases. There was nos lens luxation. Intercapsular implantation is possible without great risk. The risk of zonular rupture occurs principally during extracapsular extraction. Implants 4 to 12 times Lighter than a cataract human lens do not seem to be dangerous when there is no peroperative zonular rupture.

[Implantation in severe myopia cataract].

Based upon biometric and statistical analysis of 163 eyes (26 mm or longer), it appears that high myopia cataract occur all the earlier as the eye is long; on average, these were operated on ten years earlier than cataracts in the general population. Extra-capsular extraction and intercapsular implantation were generally used. Pre and post-operative complications are remarkably rare for such abnormal eyes. After a mean period of 22 months, detachment of the retina was observed in 1.84% of patients and secondary capsulotomy performed in 8%. Because they prevent secondary capsular opacification and anterior vitreous propagation, it appears that such barrier-type implants should be systematically placed. Current large-diameter implants allow for vitreoretinal observation. Based upon this patient population, a formula for implant power calculation specific to high myopia has been elaborated. The desired degree of refraction varies with age and patient activity.

[Keratoplasty à chaud: preliminary study].

The purpose of this paper is to review causes and follow up of 16 patients who have had a keratoplasty "à chaud" for corneal ulceration, perforation, or reviving chronically abscess, with a 9 years follow-up for a first group, and 8 months for the second. In 58%, the graft remained clear, and in 16%, the acuity was 4 to 6/10 degrees. Keratoplasty "à chaud" seems to be the most efficient method for treatment of inflammation, the most radical to restore the integrity of the eye, and can give oftentimes an accurate optical result.
