Resident surgeon efficiency in femtosecond laser-assisted cataract surgery

Figures & data

Table 1 Summary of performance time analysis of conventional phacoemulsification group and femtosecond laser pretreatment group

Interval	Conventional phacoemulsification		FLACS		Absolute difference		P-value
	M	SE	M	SE	M	SE
Total OR time	68.59	5.66	75.61	6.08	7.02	3.02	0.02
Operative time	42.59	4.74	49.96	5.07	7.37	2.45	0.001
Incision	3.82	0.12	4.60	0.31	0.79	0.31	0.01
Anterior capsulotomy	3.23	0.18	1.38	0.15	1.84	0.42	<0.001
Nucleus removal	12.54	0.48	12.73	1.05	0.19	1.15	0.87
Cortical removal	5.37	0.27	6.17	0.86	0.80	0.71	0.26
IOL placement	0.93	0.05	0.96	0.11	0.02	0.12	0.86

Notes: All times are shown in minutes. Due to patients being nested within operating residents, significance (P-value) was determined using a multivariable linear mixed-effects model controlling for patient age and allowing random intercepts for each resident surgeon.

Abbreviations: FLACS, femtosecond laser-assisted cataract surgery; IOL, intraocular lens; M, mean; OR, operating room; SE, standard error of the mean.
