Purpose
To compare the efficacy, effects, safety of phacoemulsification between active-fluidics system (AFS) with gravity-fluidics system (GFS) in patients with traumatic lens subluxation combined with traumatic cataract.
Setting
Eye and ENT Hospital of Fudan University, Shanghai, China.
Methods
Patients aged 20 years or older who were diagnosed with traumatic lens subluxation combined with cataract were included in this study. Indicators of surgical efficiency included the cumulative dissipated energy (CDE), ultrasound time (UST), total aspiration time (TAT), and estimated fluid usage (EFU), while the number of occlusion break surge times intra-operation was evaluated as the anterior chamber stability. The main effect included the postoperative best corrected distance visual acuity (BCVA) and the safety outcomes included: IOP, endothelial cell density (ECD) and central corneal thickness (CCT). Subsequently, the patients in the two groups were stratified based on nuclear hardness ≥ nuclear color (NC3).
Results
A total of 49 eyes were enrolled in the AFS group and 23 eyes in the GFS group. The CDE, UST, TAT and EFU of the AFS group were less than that of the GFS group, while the differences were not statistically significant. The number of occlusion break surge times was significantly different between the two groups (P = 0.047). Although no significant difference existed in BCVA and IOP postoperatively, the percentage of loss in postoperative ECD was significantly lower in AFS group (P = 0.0056). In eyes with nuclear hardness ≥ NC3, the CDE, UST and EFU of the AFS group were significantly less than that of the GFS group (P = 0.0076, 0.0109, 0.0234, respectively), while no significant differences were detected in eyes with nuclear hardness < NC3.
Conclusions
In patients with traumatic lens subluxation combined with cataract, AFS can achieve satisfactory clinical results comparable to GFS in terms of the efficacy and the main effect. In eyes with cataract nuclear hardness ≥ 3, AFS improves the efficiency, anterior chamber stability and safety of phacoemulsification compared with GFS. It is worthwhile to promote its application in cataract surgery in these patients.
