Methods
A prospective experimental study was conducted at the Cole Eye Institute in Cleveland, Ohio. Inclusion criteria for the study group included deficient stereoacuity (80 seconds of arc or less on the Titmus stereotest; Stereo Optical Company, Chicago, Illinois, USA) and binocular best-corrected Snellen visual acuity of 20/40 or better. Inclusion criteria for the control group included normal stereoacuity (60 seconds of arc or more on the Titmus stereotest), best-corrected Snellen visual acuity of
Results
A total of 42 patients were recruited into the study: 21 patients with deficient or absent stereoacuity and 21 control patients with normal stereoacuity. Results are given in Table 1. The mean age of the 42 subjects was 31.5 years (range, 10 to 64 years). The median and mean ages were 30 and 32 years, respectively, in the study group, and 29 and 31 years, respectively, in the control group. Of the 42 subjects, 29 (69%) were male, 15 within the study group and 14 within the control group. Based
Discussion
To date, several medical fields have used simulation techniques in training and evaluation of students, residents, fellows, practicing physicians, and paramedical personnel. Simulators in cardiovascular and pulmonary systems, resuscitation, and anesthesia have been reported as realistic representations that may assist in resident training while avoiding the risk of complications potentially associated with inexperience.7, 8, 9 Recently, advances in this field have resulted in virtual reality

2015, Journal of Cataract and Refractive SurgeryCitation Excerpt :Previous studies did identify an advantage of stereoscopic vision for tasks performed under a cataract surgery simulator. Sachdeva and Traboulsi13 found that subjects with a lifelong deficiency or absence of stereovision performed consistently worse than controls with normal stereoacuity. As in our study, the subjects had no previous surgical experience.

2014, SurgeonCitation Excerpt :A literature review in 2008 concluded that there was no evidence to conclude that stereopsis was necessary for satisfactory performance in ophthalmic surgery.5 Several studies have approached this topic using surgical simulators to examine the relationship between stereoacuity and performance on generic surgical skills,6 intraocular techniques7–10 and laproscopic dexterity.11 These have tended to show inferior performance for subjects with deficient stereopsis, however the subjects were generally surgery-naïve and the tasks were therefore unfamiliar.

2011, Journal of Cataract and Refractive SurgeryCitation Excerpt :However, catching a ball is not comparable to performing cataract surgery, and stereoacuity is only 1 factor that determines surgical skills.14,15,18 Furthermore, there is great variation within the group of individuals with deficient stereoacuity, and some of them can perform on the same level as those with normal stereoacuity.6,7,19 Further studies are therefore needed to evaluate the longitudinal effects of stereoacuity on microsurgical skills learning.
