In this paper I report the two cases of Dannheim´s anterior chamber lens operation in the monocular aphakic patientt for the first time in Korea.
The first case(19 years old male patient with traumatic cataract in his left eye) had . been operated on July 10, 1960. After operation his corrected visual acuity was 0.8 wearing glass (Sph. +12.OOD.). On Aug. 25, 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. SOD. Rad. 7.8) and LO.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.
