Comparison of the Neodymium-doped Yttrium Aluminum Garnet Capsulotomy Rate with Viscoimplantation and the Hydroimplantation Intraocular Lens Technique

Abstract

Purpose To investigate the rate of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser capsulotomy in the hydroimplantation intraocular lens (IOL) technique. Methods This retrospective study was comprised of 6,192 eyes in 3,790 patients who underwent surgery from January 2013 to September 2017 and then were followed up for at least 1 year. The eyes of these patients were divided into two groups: either viscoimplantation or hydroimplantation. The follow-up examinations were carried out on the 1st day, 4th day, 1st month, and 3 months to 1 year postoperatively. The Nd:YAG capsulotomy rates were evaluated by the different IOL implantation techniques and IOL materials. Results The mean follow-up duration of the patients was in the viscoimplantation group 14.85 ± 2.43 and 15.05 ± 1.93 months in the hydroimplantation group. The Nd:YAG capsulotomy rate was significantly lower in the hydroimplantation group compared with the viscoimplantation group for the entire hydrophilic IOL model ( p < 0.001). In addition, the Nd:YAG rate was lower in the hydroimplantation group that used a hydrophilic IOL than it was in the viscoimplantation group, which used a hydrophobic IOL. Conclusions The hydroimplantation technique reduced the Nd:YAG capsulotomy rate.

Evaluation of posterior capsular opacification and neodymium-doped yttrium aluminum garnet capsulotomy rates in patients with hydrophilic intraocular lens implantation with and without ocular viscoelastic device

“…No significant difference was observed in BCVA at the end of the study between the two groups (0.02 and 0.03 LogMAR in the OVD and control groups, respectively, P = 0.333), which supports the findings by Oğurel et al . [ 19 ] No changes in PCO morphology were observed in the two study groups.…”

“…[ 17 18 ] Moreover, Oğurel et al . [ 19 ] postulated that the irrigation fluid injected between the IOL and posterior capsule creates a jet flow, which removes LECs from the equatorial area. IOL rotation caused in the absence of OVD draws LECs and remnant lens fibers from the equatorial area and posterior capsule, respectively, mechanically, which reduces the PCO rate.…”

“…Oğurel et al . [ 19 ] retrospectively analyzed the ND: YAG capsulotomy rate in patients in whom IOL was implanted under OVD and BSS. The authors found that the ND: YAG capsulotomy rate was lower in patients who underwent hydrophobic IOL implantation under BSS than in those who underwent IOL implantation under OVD.…”

“…Unlike the present study, Oğurel et al . [ 19 ] used OVD throughout the procedure in both groups, except for the IOL implantation stage during which BSS was used. Moreover, hydrophobic IOL was used and compared between the groups that already had a negligible PCO rate.…”
