Bilateral early capsular block syndrome following implantation of the new trifocal toric lens

A young patient underwent phacoemulsification with endocapsular implantation of trifocal toric lens in both eyes (AT LISA tri toric 939 MP, Carl-Zeiss, Germany). One-week postsurgery, he developed capsular block syndrome (CBS) in both eyes. There was deterioration of uncorrected visual acuity at 1-week postsurgery, with a myopic shift of 2.5 diopters (D) in the right eye and 2.0 D in the left eye. The intraocular pressure was only elevated in the left eye. Neodymium: yttrium-aluminum-garnet laser posterior capsulotomy resolved the block successfully in both eyes. A thick lens with a plate haptic design may have contributed to the early CBS
