Pseudophakic ametropia managed with a phakic posterior chamber intraocular lens.

We report the use of a phakic posterior chamber intraocular lens (IOL) to correct pseudophakic ametropia. Two eyes of 2 patients developed ametropia after unilateral phacoemulsification and IOL implantation. The manifest refraction was -6.00 -0.50 x 50 in the first patient and +4.50 -1.00 x 15 in the second. Both patients were bothered by the induced anisometropia and had posterior chamber phakic IOL implantation in the pseudophakic eye. Postoperatively, uncorrected visual acuity improved from 20/400 to 20/30 in the first patient and from 20/200 to 20/40 in the second patient. The manifest refraction was -0.50 -0.75 x 55 and +1.50 -1.50 x 30, respectively. No complications were noted. Implantation of a phakic posterior chamber IOL may be an alternative to currently available methods of managing pseudophakic ametropia.

[Mortality and birthdays].

The authors study the date of death in relationship, in the annual cycle, to date of birth of every person who died of natural causes in Switzerland between 1st January, 1969 and 31st December, 1992 (N = 12,275,033). They highlight a maximal mortality (17% over expected) on the actual anniversary of birth with the entire population, a slightly lower figure being found under 80 years of age, higher over this age. They tie this phenomenon to the classical group of "anniversary reactions", in which problems of identity probably play a role. An uncertainty hangs nevertheless over the value of these findings, which are not confirmed by any published material, and even denied by some.

[Informed consent in the framework of biomedical research: a survey].

Inquiry on the quality and steps taken to obtain informed consents for biomedical research projects, based on the cases of 39 patients coming from 15 different projects with immediate therapeutic goals and 16 healthy subjects coming from 4 different projects without immediate therapeutic goals. Comparison between observed reality and the more or less demanding norms that were recommended. We noted a much bigger gap (therefore a consent actually informed in a lesser way) in the group of patients than in the group of healthy subjects. Explanatory hypotheses: the healthy subjects' higher social and cultural level, but also the investigators' difficulty and comprehensible discomfort to integrate, with respect to the patient, the essentially different and possibly contradictory points of view of scientific research and medical care; the "double market" notion.

[Comparison of astigmatism due to ambulatory cataract surgery with 3 different techniques].

We show that there was little difference in the average astigmatism induced in three surgical groups (Extracapsular (EC), Phacoemulsification with and without scleral tunnelization) at the last control. An examination of a second group of patients shows a significant reduction in the time necessary for recovering at least 80% of the final visual function and a significant shortening of the time elapsed before the prescription of the glasses in the group of patients operated on using phaco with tunnellization. Just as there is a significant relationship between the post-operative cyclinder and postoperative phase 1, there is also a reduction in, and early and lasting stabilisation of, the cyclinder induced by surgery using small incisions. We show that the technique of vectorial calculation brings into play discontinuous trigonometric functions that require great prudence when interpreting statistics of cylinders induced by surgery.

[Benefits of ambulatory surgery in cataract surgery].

We monitored 300 patients who had undergone ambulatory cataract operations. Patients are more and more preferring this type of surgery, which allows them to go home immediately after the operation. We compare ambulatory ECCE and phacoemulsification operations and their complications, advantages and disadvantages. We shall not go into the real cost-saving benefits of this type of surgery compared with conventional surgery, as these have already been demonstrated in other countries. Ambulatory surgery requires that the patient is to be monitored after the operation, which is difficult to do in large centers. We explain the reasons for this. We discuss the indications and contra-indications of this type of cataract procedure.

[Phacoemulsification: technical initiation at what price?].

Phacoemulsification of the cataract is perhaps technically superior which is considered "classic". This technic consists however of a number of difficulties that may be mastered during an apprentiship. Considerable complications may arise during this initiation periods; imposing this surgical method on patients is thus an ethical problem. If the risks encountered during the apprentiship of phacoemulsification appear comparable to those during the classic extracapsular technique, phacoemulsification may be recommended with less reservation. We have compared 250 initial cases of classic extracapsular extraction with 250 "initial cases" of phacoemulsification, taking into account operative and post-operative complications and final functional results.

[Development and concept of a new operatory chair].

We present a novel type of operatory chair which directs an operation microscope by remote control using infrared beams: XV, zoom, focal and accessories. The advantage of this system is the absence of transmission cables, and consequently represents an important improvement in terms of flexibility. It is a vast improvement as well for maintaining sterile conditions in the operation room. The ergonomics of this chair was especially designed for microsurgery. The adjustment and stability of the forearm has been considerably improved.

[The eye as an art form: the ocular prosthesis].

The technique of fabricating an ocular prosthesis out of glass is a rare art originating from Thüringen (formerly DDR). This technique is still practised by a few artists. A close collaboration between the ocularist and surgeon is indispensible towards achieving an optimal adaptation. We present several rules of plastic surgery enabling the cavity to receive the prosthesis after enucleation. The realization and adaptation of such a prosthesis has been filmed and will be presented.

Psychotherapeutic treatments evaluated with two instruments: clinical questionnaire and semantic differential.

We evaluated about 100 psychotherapeutic treatments on the Freudian model with two independent instruments: a clinical questionnaire (assessed globally and intuitively) and a semantic differential (processed through various mathematic analyses). The results obtained with the two instruments were compared, and we also compared the semantic evolution of patients with that of normal subjects. Both instruments show an undeniable average improvement among patients. The semantic differential also shows that the various 'zones' tested by the inducive words are neither equally affected by neurosis nor equally modified by treatment.

[Epidemiology of psychotherapies].

Report dealing with the descriptive epidemiology of psychotherapies. Enumeration of the stages which have to be taken into account: potential demand (or needs of the population), expressed demand, indication, realisation, outcome. Presentation of certain facts known today on the distribution of the population at these different stages according to sex, age and socio-cultural status. Reflections and comments on methodological points (particularly, necessity to include the psychotherapies of private psychiatrists) and on the utility of the descriptive epidemiology of these treatments, from a theoretical as well as from a practical point of view.

Application of Osgood's Semantic Differential to the study of psychotherapeutic treatments.

Osgood's Semantic Differential was applied to a group of 35 neurotic patients at initial and final stage of individual psychoanalytical psychotherapy. When compared to 'normal' subjects who had not undergone treatment but were examined under the same conditions, neurotic subjects showed, between test and retest, more conspicuous semantic changes, several of which--although not all--brought them closer to normal subjects.

[Changes occurring in psychotherapy measured by the Osgood semantic differential--methodologic elaboration].

General recall on Osgood's semantic differential. Motive and way of integrating it in research on the effects of psychotherapies. Report of some preliminary results from a transversal study of normal, neurotic and schizophrenic subjects and from a longitudinal study of normal and neurotic subjects. These first results strengthen the assumption that the semantic differential provides an appreciably adequate picture of mental state, for both its stable and evolutive components.
