Abstract:
Objective: To observe the preliminary clinical effect of intraocular lens optic capture through posterior continuous curvilinear capsulorhexis in the treatment of pediatric cataract. Methods: It was a retrospective case series study. Forty-three eyes of 28 children underwent posterior continuous curvilinear capsulorhexis with posterior chamber intraocular lens optic capture to treat cataract from June 2017 to October 2018 in Qingdao Eye Hospital. Postoperative best corrected visual acuity, diopters, intraocular pressure, the position of intraocular lens, and postoperative complications were assessed. The distribution of preoperative and postoperative best corrected visual acuity was analyzed by Fisher's exact probability test. Results: Twenty-eight patients were 14 females and 14 males aged from 2 years old to 12 years old [mean age, (7±4) years]. All intraocular lenses were successfully captured in the posterior capsule. Patients were followed-up for 6.0 to 12.0 months (mean, 8.4 months). Except 2 eyes from one uncooperative child, the distribution of preoperative and postoperative best corrected visual acuity (<0.1, 0.1-<0.3, 0.3-<0.5, ≥0.5) had a significant difference (17, 17, 4, 3 eyes vs. 4, 4, 5, 28 eyes, P<0.01). At the last postoperative follow-up visit, the mean spherical equivalent was (0.21±0.74) D. Transient intraocular hypertension occurred in 3 eyes at 1 week after surgery and was controlled with stopping the use of corticosteroid eyedrops. No visual axis opacification or intraocular lens decentration or tilt was observed during the follow-up period. No other complications such as iris synechia, secondary glaucoma, retinal detachment, and cystoid macular edema were observed. Conclusions: Posterior continuous curvilinear capsulorhexis with intraocular lens optic capture is a safe and effective technique to treat pediatric cataract. It has a significant effect on the prevention of visual axis opacification after cataract surgery in children.
