Elevated intraocular pressure in secondary piggyback intraocular lens implantation. 2005

Department of Ophthalmology, Toyama Prefectural Central Hospital, Toyama, Japan.

We report 2 cases of postoperative intraocular pressure (IOP) elevation in secondary piggyback intraocular lens (IOL) implantation without history of glaucoma or ocular hypertension. A 74-year-old woman with myopic pseudophakia and a 68-year-old man with hyperopic pseudophakia received secondary piggyback AcrySof IOL implantation in their left eyes. In both patients, the left IOP gradually increased and sustained around 30 mm Hg for about 1 year. In the first, IOP continued elevating despite topical and systemic medications. There was an episode of pupillary block in the second. Gonioscopically, heavier trabecular meshwork pigmentation in their left eyes was observed. Because of this, the 2 IOLs implanted were removed and replaced by an adequate IOL and trabeculotomy was performed in the former. The AcrySof IOL has a truncated optic edge, which increases the risk for chafing the iris, resulting in pigment dispersion syndrome; thus, it would be a poor choice for a sulcus-placed piggyback implantation.

UI	MeSH Term	Description	Entries
D006956	Hyperopia	A refractive error in which rays of light entering the eye parallel to the optic axis are brought to a focus behind the retina, as a result of the eyeball being too short from front to back. It is also called farsightedness because the near point is more distant than it is in emmetropia with an equal amplitude of accommodation. (Dorland, 27th ed)	Farsightedness,Hypermetropia

D009216	Myopia	A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.	Nearsightedness,Myopias,Nearsightednesses
D009798	Ocular Hypertension	A condition in which the intraocular pressure is elevated above normal and which may lead to glaucoma.	Glaucoma, Suspect,Hypertension, Ocular,Glaucomas, Suspect,Hypertensions, Ocular,Ocular Hypertensions,Suspect Glaucoma,Suspect Glaucomas
