Abstract
BackgroundCapsule contraction syndrome (CCS) after cataract surgery causes intraocular lens (IOL) haptic flexion and IOL optic displacement in most former reports. However, there are few reports on CCS-induced deformation of the IOL optic. We report two cases of CCS after cataract surgery in highly myopic eyes and describe a previously unreported “double arch” complication.Case presentationTwo patients with history of high myopia had cataract surgery with hydrophilic acrylic plate haptic IOLs implanted in their eyes. CCS with arch shape deformation of the pupil as well as the optic of the IOL were noticed in both cases after three months, which induced refractive changes and corrected distance visual acuity (CDVA) deterioration. Visual acuity of the patients was restored by replacing the IOL from the capsular bag to the ciliary sulcus and the following neodymium: YAG (Nd:YAG) laser capsulotomy. We propose that such “double arch” change brought by CCS is related to the plate-haptic design of the IOL and the incomplete overlap between the capsular opening and the IOL optic.ConclusionsWe recommend careful IOL selection and proper capsulorhexis in patients with high myopia or with other risk factors of CCS. Early diagnosis and timely treatment of CCS are critical to prevent visual symptoms and further ocular complications.
Highlights
Capsule contraction syndrome (CCS) after cataract surgery causes intraocular lens (IOL) haptic flexion and IOL optic displacement in most former reports
We reviewed the patient’s mydriatic photograph at 1 week after cataract surgery and noticed that the inferior edge of the IOL optic was not overlapped by the anterior capsule opening (Fig. 2F)
We believe that the occurrence of CCS in both cases are related to high myopia and the IOL feature
Summary
We recommend careful IOL selection and proper capsulorhexis in patients with high myopia or with other risk factors of CCS. Early diagnosis and timely treatment of CCS are critical to prevent visual symptoms and further ocular complications.
