Purpose:
To compare the intraoperative & postoperative performance of hydrophobic acrylic and hydrophilic acrylic intraocular lenses during pediatric cataract surgery.
Setting:
SuVi Eye Institute & Lasik Laser Center, C 13 Talwandi, Kota, Rajasthan, India
Methods:
: This was a prospective randomized study. Forty eyes of 20 children (age 6 month to 4 years) with congenital or developmental cataract were included. Children were randomly divided into 2 groups. All participants underwent phacoaspiration, primary posterior capsulotomy, and anterior vitrectomy. Group A (n = 20) eyes were implanted with acrylic hydrophobic (AMO TECNIS 1 Piece) intraocular lenses (IOLs), and those of Group B (n = 20) were implanted with hydrophilic acrylic IOLs (IOC Intraocular Care). The children were evaluated for anterior chamber reaction, IOL position, visual axis opacification, intraocular pressure, best-corrected visual acuity (BCVA), corneal status, and refractive errors.
Results:
: Mean age- 2.2±1.8 years in the hydrophobic acrylic group and 2.7±1.3 in hydrophilic acrylic group. Mean follow-up period was 18.6±5 (12-28) months. No intraoperative complication seen in any group. Postoperatively, all IOLs were in the capsular bag. None of the eyes showed glaucoma. Mean postoperative spherical refractive error was +3.25±1.50 (D) in the hydrophobic acrylic group and +3.50±1.25 D hydrophilic acrylic in the group. Visual axis opacification/ cell deposits on IOL surface at 1 year follow-up was more common in eyes implanted with hydrophophilic acrylic IOLs (8 eyes) than hydrophobic acrylic IOLs (2 eyes).
Conclusions:
: In pediatric eyes undergoing lens aspiration with primary posterior capsulotomy and anterior vitrectrectomy both foldable hydrophilic & hydrophobic IOLs design performed well in terms achieving secure in the bag fixation using a small incision. However, foldable hydrophobic acrylic IOL was found to be suitable for minimizing LECs proliferation & maintaining a clear visual axis. FINANCIAL DISCLOSURE?: No
