In this paper I report the two cases of Dannheim's anterior chamber lens operation in the monocular aphakic patient for the first time in Korea. The first case(19 years old male patient with traumatic cataract in his left eye) had been {)perated on July 10, 1960. After operation his corrected visual acuity was 0.8 wearing glass (Sph. +12.00D.). On Aug. 2S, 1960 he had taken another operation for the insertion of Dannheim's anterior chamber lens (power; +12.50D., size; 12.5mm.). On Oct. 8. 1960 the visual acuity was 0.9 with adding Sph. -5.50D. glass in front of his left eye. Through the slit lamp examination the loop of the anterior chamber lens was well fixed into the chamber angle and remained in situ. He has carried a very comfortable life without any remarkable trouble for 16 years untill nowadays. The second case (50 years old male patient with senile cataract complicated by secondary glaucoma in his left eye) had been operated intracapsullary on Jan. 15, 1960. After cataract operation he had used corneal contact lens and his corrected visual acuity for distant was 1.5 (Sph. +14.50D. Rad. 7.8) and I.O.P. was within normal limit. 9 years after cataract operation he refused to wear contact lens due to discomfortness and therefore he had reoperated to insert Dannheim's anterior chamber lens (same as case 1.) on Sept. 10. 1969. After operation his visual acuity was 0.8 for distant vision, but slight movement of the anterior chamber lens was noticed by slit lamp examination. On Jan. 12. 1970. he had had moderate iritis and slightly elevated I.O.P. (20.6mmHg.). Those symptoms had subsided after 7 day's treatment by local instillation of 2% T-pilocarpine sol. and oral acetazolamide and corticosteroid medication. On March 7, 1973. he revisited my clinic due to a severe ocular pain in his left eye. At that time the I.O.P. was 30mmHg. and the visual acuity was reduced to 0.04 due to severe anterior uveitis. And so I removed the anterior chamber lens on March 8. 1973. The Fixation of anterior chamber lens into the filtration angle is very important factor for the determination of the prognosis of operation. The continuous experiment and development of the method to fix the loop of the anterior chamber lens into the filtration angle is required for the sake of successful operation.

Extended wear soft contact lens will be the fascinating idea among the contact lens wearers in near future. A contact lens that is to be left on the eye surface during periods of sleep must achieve a degree of ocular compatibilities not previously encountered in contact lens practice. In this paper I report the clinical studies of Permalens, that is made by Global Vision, England, in 6 aphakic patients. During the 4 months periods of follow-up studies, all patients ara using their lenses very comfortably and no specific complications are found until now.

7 cases of monocular senile cataract patients have received intraocular lens implant: operations. Among the 7 patients, 4 males and 3 females are included and the mean age was 63.7 years old. The operations were performed during the period between Aug, 1978 to Oct, 1979. The mean visual acuity after IOL implant was 0.62 and there is no difference from other repoters for postoperative visual improvements. Binocular visual functions are well maintained in all cases by the Titmus test. The final results with iridocapsular lens implantation after extracapsular cataract extraction reveaeld very encouraging facts although the observation periods were too short.

Cataract and refractive surgical procedures are now among the most common and successful surgeries in medicine. A clear understanding of the current situation and future trends in these fields has become increasingly important. Since 1995, we have annually surveyed the members of the Korean Society of Cataract and Refractive Surgery(KSCRS)on cataract surgery technique, anesthesia, intraocular lens and refractive surgery. 4th annual survey forms consisted of 73 multiple-choice questions mailed in February 1999 to 176 ophthalmologists of the KSCRS. Approximately 47% of the sent out questionnaires were returned by the March cutoff date. Current data were compared with previous annual survey and data from Japan and USA. Hospitalized period is decreased annually and use of topical anesthesia(42%) increased greatly. Self sealing wound construction was the main wound closure technique in phacoemulsification accounted for 73%. Most preferred intraocular lenses for small incision cataract surgery are silicone(47%), PMMA(38%)and acrylic(15%). Viscoelastics(33%)produced by Korean medical company becomes widely used compared with previous year. Sixty eight percent of the respondents were performing excimer laser keratotomy for refractive surgery. Most preferred diopter for differentiation PRK from LASIK was 5 diopter. From this survey, we found current trend and change in cataract and refractive surgery in Korea are similar to those of Japan and USA.
