Experienced Ophthalmic Surgeons More Efficient

Motion analysis technology may be useful in surgical training

TUESDAY, Sept. 12 (HealthDay News) -- Experienced ophthalmic surgeons take less time and use fewer hand movements to perform a corneal suture than less experienced surgeons, according to a motion analysis study published in the September issue of the Archives of Ophthalmology. The technology could be useful in surgical training or as a way to assess dexterity.

Ara Darzi, M.D., of Imperial College in London, England, and colleagues examined the skills of 30 surgeons performing a corneal suture on an artificial eye using a surgical assessment device containing motion sensors. The surgeons were evenly divided among novices (those who had performed fewer than five previous sutures), trainees (five to 100 previous sutures), and experts (more than 100 previous sutures).

The researchers found that with increasing experience, there were significant drops in the time taken to complete the task and the number and path length of hand movements. There was also less variability within each group with increasing experience, according to the study.

"Motion analysis measured by this technology may be useful in the formal surgical training of residents and as an objective quantitative measure of dexterity," the authors concluded.
