“…This form of survey is, however, necessary to standardize answers and describe trends. David Leaming has surveyed members of the American Society of Cataract and Refractive Surgeons yearly since 1984 (Leaming 1998), and Tetsuro Oshika has surveyed members of the Japanese Society of Cataract and Refractive Surgeons yearly since 1992 (Oshika, 1998). The rapid evolution of the cataract operation during the last years has resulted in an increased interest in the availability of information about practice styles and preferences of colleagues.…”

ABSTRACT. A survey of the preferred techniques and choices in cataract surgery of the members of the Danish Ophthalmological Society with address in Denmark was performed in January 1998. Only ophthalmologists performing cataract surgery were asked to return the questionnaire. Ninety-one responses were received by the cut-off day, representing 28 872 cataract operations per year. The data were compared to data from previous surveys in Denmark, and similar data from the US and Japan. ) I have performed a yearly survey of practice styles and preferences of Danish cataract surgeons. Like the previous surveys, the present questionnaire asked about the preferred methods, techniques and styles of cataract surgery. Most of the questions were repeated to analyze trends, but since these issues are in continuing evolution, the topics were adjusted to the present state of art, and a few new subjects were added.In order to standardize the title of this year's survey with similar surveys from the US (Leaming 1998) and Japan (Oshika, 1998), the present paper was entitled as the 1997-survey, describing trends of cataract surgery performed in 1997. Material and MethodsFrom the Danish Ophthalmological Society and the Danish Medical Association I received a list of those members of the Danish Ophthalmological Society, who have address in Denmark. These members were sent a questionnaire of 31 multiple choice questions about practice styles and preferences concerning cataract surgery. Only those ophthalmologists who were performing cataract surgery were asked to return the questionnaire. ResultsNinety-one respondents returned the 1997 survey. The previous years, the surveys were returned by 74, 85 and 90 ophthalmologists, respectively.The volume of operations performed by the individual surgeons is shown in Fig. 1. If the mean number of surgeries within the groups is used, it can be calculated that the returned answers represent 28 872 cataract operations per year, distributed with 15 156 surgeries (52%) at public hospitals, 6708 surgeries (23%) in private practices, and 7008 surgeries (24%) by ophthalmologists operating both at public hospitals and in private practice.The exact number of cataract operations performed in Denmark is not known. Cataract patients are operated on in public hospitals and in private practices, paid by public health insurance. In addition, some patients are operated on by public hospital staff and in private practices, paid by themselves. The National Board of Health has recorded the number of cataract operations performed in 1996 at public hospitals to 18 440, and the number of operations performed in private practices, paid by public health insurance, to 2079. If half of the operations performed by public hospital staff operating both at public hospitals and private are covered by public health insurance, and the other half is paid by the patients themselves, the present data represents 18 660 operations at public hospitals, a number very close to the data from the National Board of Health.

“…Phacoemulsification and aspiration is a safe and widely practiced technique in cataract surgery [1,2]. Much attention has recently been focused on no-stitch [3,4] and corneal incision cataract surgery techniques [5,6], which take advantage of small incision cataract surgery methods using a foldable intraocular lens and small size polymethylmethacrylate intraocular lens.…”

We developed a method to measure wound temperature during phacoemulsification with a thermometer and compared the temperature between pulse and nonpulse modes. In cases with partial or complete obstruction of the aspiration port, wound temperature was significantly lower in the pulse mode versus the nonpulse mode. It was ascertained that pulse mode phacoemulsification prevents thermal burn of the wound in the hard nucleus during cataract surgery. This method is useful to evaluate wound temperature during phacoemulsification under various conditions.

“…In 1997, 96.3 % of all cataract operations in Finland were done using the phacoemulsification technique (Sandberg 1998).

ABSTRACT. (Oshika et al. 1996, Hansen 1997, Leaming 1998. The results of the survey of practice styles and preferences among Finnish cataract surgeons are presented here. Materials and MethodsIn June 98, a questionnaire of 36 multiple choice questions about practice styles and preferences in cataract surgery was sent to 153 ophthalmologists in Finland. The questionnaires were anonymous and included a return envelope. In three weeks, 75 respondents returned the questionnaire (49%), and of these 68 (44%) reported doing cataract surgery. The answers from the questionnaires were collected manually by an independent party in order to avoid revealing any surgeon's practice style or preferences to the author. The results are also compared to corresponding results from the year 1997, when 87 responses were received (46 % of all sent questionnaires, results not published earlier). Results SurgeonsThe majority of the respondents were 40-49 years of age (39.7%), although the age group 50-59 was almost as large (35.3%, Fig. 1). The respondents were distributed throughout Finland quite evenly in all five different university hospital districts (12, 13, 22, 26 and 27 %). Fifty-seven percent of the respondents were working at communal hospitals, 16 % in private hospitals and 26 % in both private and communal hospitals. Surgery volumeFifty percent of the respondents performed 26-50 cataract operations per month. Those who performed 16 to 25 or over 51 operations per month were the second largest groups, representing both 20.6% of all respondents (Fig. 2). The surgery volume distribution per month was similar in all age groups between 30-39, 40-49 and 50-59 years of age. Compared to results in 1997, there is a slight tendency towards higher volume surgeons. From the results, it can be calculated that these surveys represented almost 28 000 cataract operations in 1997, which was approximately 79% of all performed cataract operations in Finland in that year, and over 24 000 cataract operations in 1998, which is roughly 70% of the estimated cataract operations in 1998. Anesthesia techniquesIn 1998, topical anesthesia increased to most preferred anesthesia type (48% of the respondents), in 1997 it was preferred by 37.6% of the respondents (Fig. 3). The preference for peribulbar anesthesia decreased from 45.2% in 1997 to 30.7% in 1998. Use of topical anesthesia increased as the surgical volume increased. For those who performed over 51 operations per month, 64.3% preferred topical anesthesia (Fig. 4).
