Abstract
Purpose: :
to realise weather practice make a difference in the effects of caffeine during performing vitrectomy with internal limiting membran peeling (ILM).
Methods: :
vitrectom simulator (Eyesi VR Magic) was used to measure the time needed and the points given by the simulator for the surgical achievement in internal limiting membrane peeling without caffeine, and after 200-400-600-800 miligramms of caffein intake, per os. The ophthalmology specialist does not have any experience in vitrectomies, but does in anterior segment surgeries before. Two years later, after getting experiences in field of vitrectomies the measurments were repeated. The simulator gives chance in fourty-two levels of eight different courses. All the five levels of the ILM training courses’ datas were used to compare. Five-five tests were done per level, per caffeine dosage.
Results: :
both before and after getting experienced in posterior segment surgery the significantly best results were reached even in points (91±2.2 for the first time and 94±0.8 for the second time) and in needed time (187 ± 7.6 sec for the first time and 143± 7.6 for the second time) after taking 400 mg of caffeine. The significantly worst results appeared after 800 mg caffeine (points: 78±5.2 for the first time and 81±1.8 for the second time, needed time: 227 ± 11.6 sec for the first time and 179± 11.2 for the second time ). (p<0,005)
Conclusions: :
Using simulators in learning curve of vitrectomy seems to be a good possibility for getting experiences without any risk for patients. There was not any diffenence in caffeine effects on the surgeon with or without practise. We can conclude neither high intake nor total abstinence of caffeine lead to good results in our case. One can realise which is the best condition for a surgent during operation considering to caffeine intake.
