Aphakic Retinal Detachment: Management of the Fellow Eye

Abstract: One hundred eighty-five patients with unilateral aphakic retinal detachment were studied to determine the frequency of retinal detachment in the fellow eyes undergoing cataract surgery. It was found to be four times higher than the frequency in those eyes that remained phakic (26% vs 7%). Despite the high incidence of detachment, 94% of the aphakic group had a final visual acuity of 20/60 or better in the second eye. At the time of surgery, the macula was still attached in only 17% of the 185 first eyes as compared to 57% of the 21 second eyes that developed an aphakic retinal detachment.

Method for the manufacture of intraocular lenses

Abstract: Methods and apparatus are disclosed for the manufacture of plastic intraocular lenses of the type used for transplant in the human eye for natural lens replacement in cataract surgery. The novel methods and apparatus of the present invention are characterized in that the lines or wires used as retention loops are attached to the plastic lens bodies by fusing the ends thereof internally of the lens body in a position remote from the outer peripheries of the lens bodies but outside the central areas of vision of the lens bodies, one method of fusing the ends of the wires to the lens bodies being by heating the wires and pushing them into the lens bodies.

Cataract surgery performed before 800 B.C.

Abstract: The general belief that the technique of cataract extraction in India in the Sushruta period (800 B.C.) was couching is no longer tenable. A study of the original text suggests that the method was more closely allied to the extracapsular extraction of recent times.

Out-patient cataract surgery.

Abstract: A randomized prospective study of 100 consecutive cataract operations was designed to ascertain the need for hospitalization for this procedure. The results clearly indicate that immediate ambulation and discharge of the cataract patient do not detract from the very high success rate of this operation. The random nature of this study adds strong support to those surveys that have similarly concluded that hospitalization and postoperative restrictions are not necessary for the great majority of cataract patients.

[Cataract surgery and trabeculectomy at the same time (author's transl)].

Abstract: It is not unusual to observe in the same eye a chronic glaucoma and a cataract. Surgery may be indicated for one of these diseases separately or for both of them. For simultaneous operation on glaucoma and cataract several attitudes could be discussed: a) cataract surgery and medical treatment of glaucoma, b) glaucoma surgery at first and then cataract surgery, c) cataract and glaucoma surgery at the same time. Since trabeculectomy is used for glaucoma surgery, the author performs the combined method, i.e. the simultaneous lens extraction and the operation of glaucoma through trabeculectomy. The advantages of trabec-lectomy over the other techniques for glaucoma surgery indicated that trabeculectomy over the other techniques for glaucoma surgery indicated that trabeculectomy is the best technique to be used in association with intracapsular cataract extraction. Our material consists of 65 patients, amongst which there are 11 patients with diabetes. 91 eyes have been operated upon during the last 2 years. Most of the postoperative complications, i.e. hyphaema, vitreous haemorrhage and prolapse, pupillary block, postoperatve rise of i.o. pressure are not severe and have no influence in the desired fall of i.o. pressure. It may be pointed out that a permanent regulation of i.o. pressure often occurs only 3 months postoperatively. Finally it can be said that the trabeculectomy associated with intracapsular cataract extraction appeared to be the best operation in case of glaucoma and cataract, provided that on the one hand the vascular status of these patients is controlled and on the other hand the operation microscope is exclusively used in surgery of the trabeculum.

Intraocular lenses: one hundred consecutive cases of intracapsular cataract extraction with Copeland iris plane lens implantation.

Abstract: A series of one hundred consecutive cases of intracapsular cataract extractions with insertion of the Copeland iris plane intraocular lens implant are presented. The preoperative management, surgical technique, and postoperative management are discussed in detail. Complications that may arise during surgery, early postoperative phase (first week), convalescent period (one to six weeks), and early long-term phase (1.5 through eight months) are presented and discussed. Short-term results to data have been most gratifying. The incidence of surgical complications closely parallels any consecutive series of one hundred intracapsular cataract extractions without lens implantation. The usual problems associated with adjustment to aphakia (particularly unilateral) are eliminated to the relief of patient and surgeon. The level of patient satisfaction is extremely high in comparison with standard cataract surgery. Elderly patients experience a sense of social rejuvenation that is phenomenal.

[Late results of cataract surgery after oculopression (author's transl)].

Abstract: By the hypotonisation of the eyeball with an oculopressor the loss of vitreous during the cataract extraction can be almost always avoided. The anatomic and functional results are discussed from 65 cases examined at follow-up. The further supervision should not be neglected as also recommended in cases of cataract extractions without previous oculopression.

Cataract surgery: review of 500 consecutive cases.

Abstract: We believe that most cataract extraction procedures may be good in competent hands, but that complicated techniques do not necessarily give the best results. With inexperienced residents, or the occasional surgeon, a safe, simple method needs to be used until the skill of the operating surgeon may warrant more advanced techniques. A simple cataract procedure consisting of local anesthesia, limbal-based conjunctival flap, 3 postplaced 7-0 mildly chromicized gut sutures, 2 peripheral iridotomies and tumbling extraction of the lens with capsule forceps (indirect acting) is described. The low incidence of complications of all types would seem to negate the current trend of complicating the procedure. Further reports will include large series of cataracts done by resident physicians rather than by the instructors to try to further justify this position.

The absorbable sutures in cataract surgery.

Abstract: An unusual case of cataract extraction is presented in which 6-0 chronic catgut sutures persisted over 2 years and 8 months and caused repeated attacks of conjunctival inflammation and iritis. This along with the discussion in this paper shows that despite is other advantages the chronic catgut is not a suitable suture for routine use in cataract surgery. However, because of the distinct advantages it is suggested that its use be limited to the selected cases, eg, in nervous persons where difficulty in removal of sutures is a problem.

The future of cataract surgery

Abstract: In relation with the 1974 course of 'pseudophakia' organised by C. D. Binkhorst and J. G. F. Worst the following conclusions occur as regards the future of cataract implants. Probably during the following 10 years many cataract patients will ask for lens implants. This operation is safe with small risk only in best hands. The standard cataract surgery (without lens implantation) should be still a part in training of an eye surgeon. The implantation surgery should not be a part of basic training of an eye surgeon.

The advance and regression of the cataract operation

Abstract: In modern cataract surgery the introduction of akinesia, the corneal incision, the intracapsular extraction with forceps or cryo-stick, the zonulolysis and measures against complications and the optic correction of unilateral cataract with contact lenses can be seen as definite advances. Critically seen, the use of the operating microscope for senile cataract is not necessary, as the binocular loupe is fully sufficient. In the same way the selective use of zonulolysis - but not after the age of 55 - and of the cryo-stick - only on a stretched lans capsule is advised. Also the artificial pupillary lens is not recommended because of the excellent functional results of the contact lens. The same argument applies to emulsification of the crystalline lens. Also, from our experience, the routine use of antibiotics is not necessary. As well as the actual operation methods, including premedication, the methods used to avoid complications are finally and thoroughly discussed.
