| Summary: | Purpose:
To compare incisional fluid loss during different stages of phacoemulsification and its effect on anterior chamber stability in microcoaxial and bimanual phacoemulsification.
Materials & Methods:
This prospective randomized study comprised of 80 consecutive patients, 40 patients in each group having routine uneventful cataract surgery. All patients were operated on the same phaco machine by the same surgeon. Intra-operative parameters were constant for all patients in each group. Volume of incisional fluid leak was measured during different stages of phacoemulsification. Along with volume of fluid aspirated in cassette, total volume of balance salt solution used, frequency of visually significant surges during different stages of phacoemulsification and post-operative best corrected visual acuity & central corneal thickness were measured in microcoaxial and bimanual phacoemulsification.
Results:
The mean percentage of incisional fluid leak during nucleus removal in microcoaxial phacoemulsification was 21.22±6.07% and was 24.73±5.06% in bimanual phacoemulsification (P value: 0.006). The mean percentage of incisional fluid leak during irrigation/aspiration/polishing in microcoaxial phacoemulsification was 38.60±7.22% and was 57.70±6.59% in bimanual phacoemulsification (p value: < 0.0001). Average frequency of visually significant anterior chamber surges in microcoaxial phacoemulsification was 6 and was 36 in bimanual phacoemulsification. Postoperative mean increase in central corneal thickness (CCT) in microcoaxial phacoemulsification was 4.93±3.11 on Day 1 and was 0.70±1.11 on Day 7 and in bimanual phacoemulsification it was 9.55±4.77 on Day 1 and 1.55±1.72 on Day 7 (P value, Day 1: <0.0001 & Day 7: 0.01).
Conclusion:
Significant increase in incisional fluid loss was observed in bimanual phacoemulsification. This led to more surges during surgery along with increase in central corneal thickness in immediate postoperative period. This suggests that microcoaxial phacoemulsification has better fluidics and anterior chamber stability. |
