- Abstract
Erbium laser phacoemulsification – a pilot study Introduction From August 1997 to March 1998 a prospective pilot study was performed to examine erbium laser phacoemulsification in cataract surgery under clinical conditions and to determine the side-effects of this method. Patients and method 34 patients (40 eyes) with senile cataract were recruited. Slit lamp findings, keratometry, best corrected visual acuity, refraction, pachymetry, endothelial cell count, and intraocular pressure were determined preoperatively and on postoperative days 1, 4, 14, and 60, according to a standardized protocol (single pulse energy between 10 and 20 mJ, frequency of application 60 Hz, average phacoemulsification time 3 min, and total energy 38.5 J). The operations were done with the erbium laser system MCL 29 (Aesculap-Meditec Co., Jena, Germany). Results A total emulsification of the nucleus was possible in 36 of the 40 eyes (90%) (nucleus hardness 0–3). A partial emulsification of the nucleus (nucleus hardness 3) was possible in 2 eyes (nucleus hardness 4) in 1 eye, and (nucleus hardness 2) in 1 eye. Visual acuity increased from 0.3 preoperatively to 0.8 two months postoperatively (median). Intraocular pressure decreased from 16 mmHg preoperatively to 13 mmHg two months postoperatively (median). The increase of corneal thickness was not statistically significant compared to baseline. The decrease in endothelial cells count was 0.96%. Postoperative complications which are not known in ultrasonic phacoemulsification did not appear in erbium laser phacoemulsification. Conclusion Erbium laser phacoemulsification is a surgical method that makes the emulsification of softer nuclei under clinical conditions possible with a low rate of complications also at the beginning of the learning curve. For harder nuclei technical and surgical parameters have to be optimized. Advantages of erbium laser phacoemulsification compared to ultrasonic phacoemulsification are less energy...
