Abstract:
AIM: To observe the clinical effect of invisible anchor hook intraocular lens(IOL)fixation surgery.METHODS: Prospective and uncontrolled case study. A total of 19 patients(19 eyes)with aphakia, IOL dislocation, or lens dislocation from January 2019 to December 2020 were selected for this study, all of whom underwent anchor hook IOL scleral fixation implantation surgery. The main postoperative observation indicators are best corrected visual acuity(BCVA), uncorrected visual acuity(UCVA), corneal endothelial cell density, tilt of IOL position, and complications.RESULTS: The UCVA(LogMAR)before and at 1 mo after surgery was 1.06±0.63 and 0.40±0.26, respectively(P<0.01), BCVA(LogMAR)before and at 1 mo after surgery was 0.27±0.51 and 0.06±0.15, respectively(P=0.09), and the average corneal endothelial cell density was 2406±625 and 2004±759 cells/mm2(P=0.13). The complications that occurred at 1 d postoperatively were 2 and higher grade aqueous flare(3 eyes), wrinkling of the corneal posterior elastic layer(2 eyes), and transient elevated intraocular pressure(2 eyes). No IOL dislocation occurred during 24 mo follow-up.CONCLUSION:The anchor hook type IOL scleral interlayer fixation technique, which involves anterograde insertion and retrograde fixation of the interstitial thread, is similar to the principle of anchor hook and achieves good IOL stability and visual effects.
