What is the effect of implantation of EDOF intraocular lens in cataract patients with Fuchs endothelial corneal dystrophy

Editor's Note Fuchs Endothelial Dystrophy is an inherited corneal disease characterized by progressive loss of the corneal endothelium, thickening of the corneal Descemet's lamella, and deposition of extracellular matrix explants. Due to the loss of corneal endothelial cells in patients, cataract surgery may damage corneal endothelial cells, so cataract patients with Fuchs corneal endothelial dystrophy will have higher risks if they undergo surgical treatment, and many doctors are reluctant to take risks. such an operation. At the 40th European Society of Cataract and Refractive Surgeons Annual Meeting (ESCRS 2022) held in Milan, Italy on September 16, Dr. Ali Nowrouzi et al shared the implantation of depth of field extension for cataract patients with Fuchs Corneal Endothelial Dystrophy The case report of EDOF intraocular lens has attracted many ophthalmologists to watch. Case overview The purpose of this study was to observe the visual performance of EDOF intraocular lenses implanted in both eyes of a patient with Fuchs corneal endothelial dystrophy without functional hexagonal endothelial cells. The patient was a 77-year-old man who requested cataract surgery with a complaint of progressive vision loss. The patient denied any relevant prior medical or ophthalmologic history and had corrected distance visual acuity (CDVA) of 20/60 in the right eye and 20/40 in the left eye. Uncorrected near visual acuity (UNVA) in both eyes measured at 40 cm was 20/200. Routine preoperative evaluation of the patients' eyes was performed using ocular biometry (IOL Master-700), mirror microscopy, optical coherence tomography (OCT), and corneal topography. The patient did not have functional hexagonal endothelial cells, and the corneal astigmatism in the right and left eyes was 0.20 D and 0.54 D, respectively. Using the Barrett Universal II formula, for myopia of -0.50 D in both eyes, a 16.0 D EDOF intraocular lens was selected. The possibility of Descemet's Endothelial Transplantation (DMEK) is high. The patient underwent routine cataract surgery without any intraoperative or postoperative complications. The results of the patient's eye examination: 3 months after the study results, the patient's uncorrected distance visual acuity (UDVA) was 20/25, uncorrected intermediate distance visual acuity (UIVA) (66 cm) and UNVA (40 cm) were 20/25, respectively. 25 and 20/30. The patient's residual diopter was -0.50-0.75x105° in the right eye and -0-0.50x105° in the left eye (CDVA 20/20). The patients were satisfied with far, near, and intermediate distance vision, and no parallax was observed in both eyes. Summary Surgery for cataract patients with Fuchs endothelial corneal dystrophy is a tricky business, but judging from the results of this study by Dr. Ali Nowrouzi et al, implanting an EDOF intraocular lens in such patients may allow patients to obtain Good visual quality, patients are satisfied with far, medium and near vision, and the dependence on glasses is relatively low after surgery, which is a good treatment inspiration for cataract surgeons.
