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.
