Abstract
BackgroundTo compare the efficiency of preloaded vs manually loaded IOL (P-IOL vs M-IOL, respectively) delivery systems in cataract surgery in the largest ambulatory surgery center of Northwestern China.MethodsA total of 200 cases were included in this prospective, observational study. Time and motion data were collected in a one- or two-operating room (1-OR or 2-OR, respectively) scenario. A model of the efficiency and revenue implications of introducing a preloaded delivery system for IOLs in cataract surgery was used to estimate the changes in cataract throughput and hospital revenue through transitioning from the M-IOL delivery system to the P-IOL system.ResultsIn the 1-OR scenario, the mean total case time was 16.9 min using P-IOL, which was a 7.7% reduction compared with M-IOL (P < 0.01). In the 2-OR scenario, the mean total surgeon time was 10.8 min using P-IOL, which was a 7.8% reduction compared with M-IOL (P < 0.05). By switching from M-IOL to P-IOL, annual throughput will increase by 5.2% (960 cases) in the 1-OR scenario and 7.7% (1440 cases) in the 2-OR scenario, accompany by an increase in revenue of approx. 284,352 USD in the 1-OR scenario and approx. 426,528 USD in the 2-OR scenario.ConclusionThis report is the first of a comparison of two IOL delivery systems in China using different settings in the scenario. IOL delivery with preloaded systems is time saving in both the 1-OR scenario and the 2-OR scenario. Moreover, switching from the M-IOL delivery system to the P-IOL system holds potential to increase cataract throughput and hospital revenue.
Highlights
To compare the efficiency of preloaded vs manually loaded intraocular lens (IOL) (P-IOL vs Manually loaded intraocular lens (M-IOL), respectively) delivery systems in cataract surgery in the largest ambulatory surgery center of Northwestern China
A total of 200 routine cataract cases were enrolled in the study, of which 98 were performed with Preloaded intraocular lens (P-IOL), and 102 were performed with M-IOL
In the One operating room (1-OR) scenario (Table 2), the setup time, lens time and tear down time were significantly reduced using P-IOL compared with M-IOL (P < 0.01)
Summary
To compare the efficiency of preloaded vs manually loaded IOL (P-IOL vs M-IOL, respectively) delivery systems in cataract surgery in the largest ambulatory surgery center of Northwestern China. Cataracts remain the second leading cause of visual impairment and the leading cause of vision loss. The prevalence of cataracts is expected to increase correspondingly. In China, among people aged 45–89 years old, the number of cataract cases was 50.75 million in 1990 and 111.74 million in 2015 [3]. Wu et al BMC Ophthalmology (2020) 20:469 people aged 45–89 years old will be affected by cataracts [3]. More efficient and effective surgical techniques are needed to provide reliable outcomes and to improve cataract throughput
