Vacuum time (mean ± std. dev.) and number of intraoperative complications occurred during each Stage.

Stage	N	Surgeon	Technical staff member	Vacuum time (seconds)	Intraoperative complications
1a	50	Surgeon 1	Technician 1	137.75 ± 15.7	3
1b	50	Surgeon 1	Technician 1	99.48 ± 4.92	0
2a	50	Surgeon 2	Technician 1	115.66 ± 9.64	1
1c	50	Surgeon 1	Technician2	101.93 ± 4.79	0
2b	50	Surgeon 2	Technician 2	99.73 ± 4.72	0

Surgeon 1 is familiar and has experience with other femtosecond platforms but not with that particular one assessed in this study. As a result, in Stage 1a neither of the two staff members had any prior experience with that platform in this sense, both Technician 1 and Surgeon 1 gained their experience simultaneously and in parallel. When Surgeon 2—who had no prior experience with any femtosecond platform—joined the OR team, he partnered with Technician 1, who was already experienced since he had been involved in the first 100 cases. In subsequent Stages 1c and 2b, both Surgeon 1 as well as Surgeon 2 perform additional surgeries but with the assistance of a new Technician (Technician 2), who had no prior experience with femtosecond platforms.
