Intolerance of a non-diffractive extended-depth-of-focus IOL with mini-monovision
- Purpose: The use of a non-diffractive extended-depth-of-focus (EDOF) intraocular lens (IOL) with slight myopia of −0.5 D on the non-dominant eye increases the spectacle independence and has good subjective tolerance with optical phenomena comparable to those of a monofocal IOL. This case report describes the course of a myopic patient who underwent refractive lens exchange, didn't tolerate mini-monovision and received IOL exchange therefore. Observations: A healthy, 62-year-old male with myopia of approximately −5 D underwent refractive lens exchange with a non-diffractive EDOF-IOL on both eyes with slight myopia on the non-dominant left eye (mini-monovision). The operation was performed without any complications, postoperative treatment was due to the clinic's standard procedure. Two weeks postoperative the patient presented with uncorrected distance visual acuity of 0.0 logMAR, a subjective refraction of −0.25/−0.25/142° and corrected distance visual acuity of 0.1 logMAR on the right eye. On the left eye, distance visual acuity was 0.4 logMAR with a subjective refraction of −0.5/−0.75/9° (intended mini-monovision) and corrected distance visual acuity of 0.0 logMAR. Binocular distance visual acuity was 0.0 logMAR. The patient complained about the occurrence of optical phenomena at dim light while driving a car and subjective reduced visual acuity. After an IOL exchange on the left eye with the implantation of the same type of non-diffractive EDOF-IOL aimed for emmetropia, the patient was symptom-free and reported no more subjective complaints. Conclusions: Despite the satisfying subjective and objective visual outcome which is proven in multiple studies, the subjective perception of a mini-monovision with a non-diffractive EDOF-IOL can vary individually. A preoperative assessment of the patient's needs and tolerance of a mini-monovision is crucial for a satisfying postoperative outcome.
