“…The performance obtained with vectographic tests of the IOL analyzed in our study is comparable to that obtained in previous studies on the same lens [12,[30][31][32], phakic patients with the same age-range [12] and monofocal IOL patients (mean of 57.1± 36.9 sec arc in 100 patients) [35]. Other ways to restore near vision with IOLs such as monovision (mean of 175.6± 1.13 sec arc in 26 patients) [36] and combining refractive and diffractive lenses in the same patient [33] show worse values of stereoacuity. Threshold stereoacuity analyzed properly with the Howard-Dolman method reveals different outcomes in comparison to ours and previous literature using vectographic tests.…”

“…Whether the dominant eye is corrected for distance or near may be less crucial. 53 In patients who are unhappy with their post-operative refractive surprise, regardless of cause, surgical management options include IOL exchange, a piggyback IOL (a sulcus IOL placed in front of the existing IOL in the bag) or refractive laser surgery.…”

Modern cataract surgery is safe in more than 95 per cent of patients. In the small number of cases where a serious complication occurs, the most common is an intra-operative posterior capsular rupture. This can lead to vitreous loss or a dropped nucleus and can increase the risk of post-operative cystoid macular oedema or retinal detachment. Postoperatively, posterior capsular opacification is the most common complication and can be readily treated with a YAG capsulotomy. The most devastating complication is endophthalmitis, the rate of which is now significantly decreased through the use of intracameral antibiotics. As a clinician, the most important step is to assess the patient pre-operatively to predict higher risk individuals and to counsel them appropriately. In these patients, various pre-or intra-operative management steps can be taken in addition to routine phacoemulsification to optimise their visual outcome.

“…22,23 Monovision can be implemented with contact lenses, 22,24,25 corneal refractive surgery, [26][27][28][29] or monofocal IOLs following crystalline lens removal in cataract surgery. 20,[30][31][32] Despite decades of clinical application, the ideal degree of anisometropia in monovision is still a topic of active research. 19,20,33,34 The optimal power difference between the two eyes has been reported to vary between 1.0 and 2.0 diopters (D), depending on the need according to the patient's lifestyle or occupation.…”

PURPOSE.To investigate the impact on visual performance of modifying monovision with monocularly induced spherical aberration (SA) to increase depth of focus (DoF), thereby enhancing binocular through-focus visual performance. METHODS.A binocular adaptive optics (AO) vision simulator was used to correct both eyes' native aberrations and induce traditional (TMV) and modified (MMV) monovision corrections. TMV was simulated with 1.5 diopters (D) of anisometropia (dominant eye at distance, nondominant eye at near). Zernike primary SA was induced in the nondominant eye in MMV. A total of four MMV conditions were tested with various amounts of SA (60.2 and 60.4 lm) and fixed anisometropia (1.5 D). Monocular and binocular visual acuity (VA) and contrast sensitivity (CS) at 10 cyc/deg and binocular summation were measured through-focus in three cyclopledged subjects with 4-mm pupils.RESULTS. MMV with positive SA had a larger benefit for intermediate distances (1.5 lines at 1.0 D) than with negative SA, compared with TMV. Negative SA had a stronger benefit in VA at near. DoF of all MMV conditions was 3.5 6 0.5 D (mean) as compared with TMV (2.7 6 0.3 D). Through-focus CS at 10 cyc/deg was significantly reduced with MMV as compared to TMV only at intermediate object distances, however was unaffected at distance. Binocular summation was absent at all object distances except 0.5 D, where it improved in MMV by 19% over TMV. CONCLUSIONS.Modified monovision with SA improves through-focus VA and DoF as compared with traditional monovision. Binocular summation also increased as interocular similarity of image quality increased due to extended monocular DoF.Keywords: aberrations, presbyopia, monovision, binocular adaptive optics P resbyopia, the age-related loss of accommodation, mostly affects the population aged over approximately 50 years.

Patient satisfaction and visual function after pseudophakic monovision

Abstract: Monovision with modest refractive targets achieved good visual function and patient satisfaction without the inherent risk for troublesome visual symptoms associated with multifocal IOLs.
