To establish and evaluate a systematic training programme to be included into the ophthalmologic resident curriculum.


Medical students (n = 20) within a year from graduation and with no previous ophthalmic experience were included in this prospective study and randomized into two groups. Group A (n = 10) completed the Eyesi cataract simulator training programme once a week for 4 weeks, while Group B (n = 10) completed it once a week at the first and the last week. Two cataract surgeons were used to determine two different levels of reference scores. Score per analysed module [two different levels of Capsulorhexis (A and B), Hydromaneuver, Phaco divide and conquer], Overall score, Total time, Cornea injury, Capsule rupture and Capsule damage by ultrasound were recorded.


Group A outperformed Group B in several modules, reached a significant higher number of reference scores (p < 0.01) and caused fewer complications with regard to Capsule rupture (p = 0.01) and Capsule damage by ultrasound (p < 0.05). Both Groups A and B improved their performance and also became more time efficient (p < 0.01 for both groups). Group A showed positive learning curves for Overall score (p < 0.01), Capsulorhexis A (p < 0.01), Capsulorhexis B (p < 0.01) and Hydromaneuver (p = 0.01). Group B showed a significant improvement for Overall score (p < 0.01), Hydromaneuver (p = 0.02) and Phaco divide and conquer (p < 0.01).


Repetitive training with a systematic training programme, based on validated modules in the Eyesi simulator, was shown to improve simulated cataract surgery skills. Higher level of skills and more reference scores were reached with more training. Furthermore, the programme was optimized to be applied into the standard ophthalmological curriculum for cataract surgery training.
