Clinical Observation of Non-Staining Circular Capsulorhexis for Hypermature Cataract

Objective: To explore the circular capsulorhexis method and its clinical effect in phacoemulsification of hypermature cataract without staining. Methods: In this prospective randomized case-control study, 22 patients (22 eyes) with were randomly divided into a staining agent group (10 cases, 10 non-staining (12 12 eyes). Both groups underwent foldable intraocular lens implantation under topical anesthesia. group, 0.5% indocyanine green was used to stain anterior capsule assist capsulorhexis; after puncturing aspirating liquefied cortical material, capsular bag filled viscoelastic increase contrast prior capsulorhexis. The operability observed, capsulorhexis, diameter opening, operative time compared analyzed between two groups. Results: successfully success rate 100%. diameters opening 5.68 ± 0.15 mm 5.54 0.16 mm, respectively, any statistical difference (P > 0.05); (40.40 5.42 s) shorter than that (50.92 3.97 s), statistically significant < 0.001). both groups, successful, implanted bags; their visual acuity showed improvement during 1-month follow-up period surgery, surgical complications. Conclusion: cataract, injecting for volume replacement, given lack agent, can reduce risk large collapse on zonular ligament. Thus, it is considered safe effective. Circular conducive smooth procedure.
