The normal corneal endothelial cell count was measured by the non-contact(Nikon, AS-1, Japan) and contact type(Bio-optic, LSM 2000, USA) specular microscopy. The results of two types were compared to investigate the possible differences in types of specular microscopy. No statistically significant differences were found between the results from the non-contact type and those from the contact type; the mean number of normal Korean corneal endothelial cells according to the age was 2795 in the 2nd decade, 2615 in the 3rd decade, 2463 in the 4th decade, 2283 in the 5th decade, 2119 in the 6th decade, 2019 in the 7th decade and 1920 over the 8th decade.

PURPOSE: To evaluate corneal endothelial cell changes after conventional coaxial phacoemulsification and bimanual microincision cataract surgery (MICS). METHODS: Forty patients were divided into 2 groups, coaxial phacoemulsification (Group 1, n=20), and MICS (Group 2, n=20). To evaluate corneal endothelial cell changes after coaxial phacoemulsification and bimanual MICS, intraoperative phacoemulsification power and volume of intraoperative irrigation solution (balanced salt solution, BSS(R), Alcon, U.S.A) were measured. Central corneal thickness and endothelial cell count were also evaluated, preoperatively and at 1 week, and 2 months postoperatively. RESULTS: Between the 2 groups, there was no statistically significant difference in intraoperative phacoemulsification power and volume of intraoperative irrigation solution (balanced salt solution, BSS(R), Alcon, U.S.A.) (p>0.05). In addition, there was no statistically significant difference between the 2 groups in endothelial cell count and central corneal thickness (p>0.05). CONCLUSIONS: When comparing bimanual MICS and conventional coaxial phacoemulsification, bimanual MICS appears to have similar endothelial cell changes. In conclusion, MICS has the same safety as compared to coaxial phacoemulsification.

To measure the rate of endothelial cell loss caused by anterior radial keratotomy, twenty one eyes of twelve patients were chosen. Numbers of endothelial cells per mm2 were examined through Keeler Konan wide field specular microscope at the time of preoperative, postoperative 3 month, 6 month, and 1 year. There were only a few changes in numbers of endothelial cells, and the results were statistically significant. Therefore anterior radial keratotomy rarely cause bullous keratopathy due to significant endothelial cell loss.

PURPOSE: To access the effect of phacoemulsification using the AquaLase(R) (Alcon Laboratories, TX, U.S.A.) on corneal endothelial cell. METHODS: This study comprised 47 eyes of 43 patients having phacoemulsification with the AquaLase(R). Various corneal endothelial cell parameters, including corneal endothelial cell density, corneal thickness and morphologic change, were evaluated up to 2 months postoperatively. RESULTS: Preoperative mean corneal endothelial cell density was 2818+/-282 cell/mm2. Postoperative mean corneal endothelial cell density was 2682+/-390 cell/mm2 at 1 day, 2701+/-263 cell/mm2 at 1 month and 2721+/-396 cell/mm2 at 2 month. Corneal endothelial cell loss was 4.74%, 4.00% and 3.55% at postoperative 1 day, 1 month and 2 months respectively. There was no statistically significant difference between preoperative and postoperative corneal endothelial cell density (p>0.05). The corneal endothelial cell loss was not increased even though the phacoemulsification time with the AquaLase(R) was increased (p>0.05). Preoperative mean corneal thickness was 559.4+/-37.4 micrometer. Postoperative mean corneal thickness was 586.9+/-35.1 micrometer at 1 day, 573.3+/-30.1 micrometer at 1 month and 554.9+/-26.7 micrometer at 2 month. There was a significant increase in corneal thickness at postoperative 1 day (p=0.001). However, there was no statistically significant difference of corneal thickness between preoperative and postoperative 1 month and 2 month (p>0.05). CONCLUSIONS: The phacoemulsification with the AquaLase(R) dose not cause the significant corneal endothelial cell density and corneal thickness change postoperatively.
