We offer real benefits to our authors, including fast-track processing of papers. Cochrane Database Syst Rev. Become a Part of The Institution. Finally, the primary outcomes measure of spectacle-free vision, was achieved in a surprisingly high number of patients, given the propensity for photopsia in premium lenses. Unlike many multifocals, Vivity ($2700@) IOL supposedly reduces starburst, halo, glare etc. There was also no statistically significant difference in outcomes between patients who underwent femtosecond laser-assisted cataract surgery and those who underwent manual phacoemulsification; that bore out for each additional outcome measure as well.

Multifocal versus monofocal intraocular lenses for age-related cataract patients: a system review and meta-analysis based on randomized controlled trials. Graefe’s Arch Clin Exp Ophthalmol. Limited success has been reported after Nd:YAG capsulotomy of the nasal anterior capsule.[15]. Hood CT, Sugar A. Subjective complaints after cataract surgery: common causes and management strategies. Additionally, a detailed subjective examination includes any patient experience of bright artifacts of light described as arcs, streaks, starbursts, rings, or halos. Open access peer-reviewed scientific and medical journals. They measured photic phenomena such as halos in the form of a simulated car headlight. Other case reports have similar findings, but no large-scale studies have been done.4,16. doi:10.1016/j.jcrs.2010.11.032, 13. Negative dysphotopsia typically presents as dark, temporal arcing shadows or curtains.[1]. It is the authors’ belief that the spectacle independence achieved with the PanOptix has the potential to greatly impact patient care by providing a much higher level of spectacle independence than other lenses. Comparison was made to two previous cohorts of multifocal IOL patients who had undergone similar surgery and responded to a similar questionnaire in a similar time frame.15 In that study, the 2.5 mini-monovision cohort received the AcrySof IQ ReSTOR ActiveFocus +2.5 D or AcrySof IQ ReSTOR ActiveFocus +2.5 D add toric implant bilaterally, with the dominant eye targeted for emmetropia and the nondominant eye targeted for −0.5 sphere. Technically, the PanOptix is a quadrafocal lens in that it creates a fourth focal point at 1.20 m. This fourth focal point is not accessible to the patient, instead the light is diffracted towards distance with a goal of increasing light efficiency and creating a more natural transition between near, intermediate and distance vision [1] [2]. Yes such problems have been described, more with multifocal than monofocal or toric IOLs. • Top, © Copyright 2023 • Dove Press Ltd Probing for specific symptoms may elicit a positive response by certain patients, even in the absence of significant problems. Neodymium:YAG laser anterior capsulectomy: Surgical option in the management of negative dysphotopsia. 2. Ophthalmology. The researchers found that materials with higher refractive indices help to concentrate a larger amount of light onto a smaller area of retina, resulting in symptoms. Diagnosis and treatment of mysterious light streaks seen by patients following extracapsular cataract extraction. After a clouded cataract lens is removed, it is replaced with an artificial lens, called an intraocular lens or IOL. Overall patient satisfaction rates were higher for the PanOptix, but so were the rates of dysphotopsia. Some of the light bounces off the edge, creating one of the positive dysphotopsias. 1985;11:21e23. Bad night dysphotopsia! Ophthalmology Management. ig It indicates, "Click to perform a search". doi:10.1016/j.ajo.2013.08.019. 5. One strong hint for this etiology is finding otherwise unexplained substantial discrepancy between the corneal cylinder magnitude/axis vs manifest refraction cylinder magnitude/axis in the postoperative eye. J Cataract Refract Surg. Stephenson M. Dysphotopsia: Not Just Black and White. Lawless, Michael, et al. For most people, cataract surgery goes smoothly. ND is more complex to analyze but may benefit from improved IOL design as well as varying the surgical approach of IOL implantation. gq Posterior capsulotomy in such a setting may increase, rather than relieve symptoms. “AcrySof IQ PanOptix Intraocular Lens Versus Extended Depth of Focus Intraocular Lens and Trifocal Intraocular Lens: A Clinical Overview.” Asia-Pacific journal of ophthalmology (Philadelphia, Pa.) vol. 2011;18(10):36.

To compensate, however, we performed a subgroup analysis of patients who did meet the same refractive criteria, and there was no change in our primary or secondary outcomes (satisfaction and spectacle independence) of this study. Several different treatments to reduce negative dysphotopsia have been attempted. Negative Dysphotopsia is another name for the last symptom which is a shadow-like distortion to the side of the vision. Davison JA. Published by Elsevier Inc. J Curr Ophthalmol. [5] In the study where 93% of the 27 patients reported visual pheonomenon, 89% reported halos and 11% reported glare. Woodward MA, Randleman JB, Stulting RD. Studies report a range from as low as 1.5% to as high as 67% for positive dysphotopsias, with most data showing more moderate numbers of 12% to 35%).4-6 Negative dysphotopsias are less prevalent and are thought to occur in only 0.5% to 2.4% of patients.5,7 In the vast majority of cases, the symptoms subside several weeks after surgery due to the process of neuroadaptation. Now more than ever, patients desire to be completely free of spectacles after cataract surgery and require optimal vision at all focal points to maintain independence and productivity in the workforce.18,19 A number of advanced premium lenses have been developed to accommodate this need, including the AcrySof IQ PanOptix trifocal and the AcrySof IQ ReSTOR +2.5 and +3.0, among others. Yet, a small percentage of patients remain dissatisfied after the procedure, even if it results in 20/20 visual acuity. Masket S, Fram NR. Pseudophakic Dysphotopsia: Review of Incidence, Cause, and Treatment of Positive and Negative Dysphotopsia. 2020. Several studies report partial or complete resolution of symptoms after YAG laser anterior capsulotomy of the nasal portion of the anterior capsule.23,24 This evidence disagrees with an earlier study’s hypothesis that eventual opacification and translucency of the anterior capsule helps reduce shadow perception by scattering light into that region of the retina.19 Compared to other studies, this explanation addresses why the incidence of negative dysphotopsias decreases drastically two to three years after surgery. • Web Design by Adhesion. Organizations Working Toward the Prevention of Global Blindness Today’s cataract surgery is extremely successful at improving patients’ vision and quality of life. In this subgroup, overall satisfaction was “very satisfied” in 85% of patients with PanOptix, in 82% of patients with 2.5 mini-monovision, and in 70% with 2.5/3.0. For surgeons implanting multifocal IOLs, nighttime dysphotopsia in their patients is a concern. Nishi O. Posterior capsule opacification. There was a higher percentage of patients who underwent femtosecond laser-assisted cataract surgery in the PanOptix cohort (n=52, 88%) than in the in the 2.5 mini-monovision cohort (n=57, 56%) or the 2.5/3.0 cohort (n=18, 22%).

In support of this, Holladay et al has shown that square edges concentrate stray light into an arc on the retina opposite to the image of the light source. J Cataract Refract Surg. The term dysphotopsia is used to describe a variety of visual symptoms that result from light reflecting off the intraocular lens (IOL) onto the retina.2 Dysphotopsias are generally divided into two categories: positive and negative. Despite these advancements, residual refractive error and spectacle dependence are common complaints among patients implanted with premium lenses,10,12,14,20 and often result in patient dissatisfaction. ND occur more frequently in women, in the left eye and with in-the-bag IOLs. Jan 2020. This work is published and licensed by Dove Medical Press Limited.

Summit recommends either the 24-60" or 32-80" poles for boat use. This trial was a prospective, open-label, multicenter analysis of PROs and satisfaction among patients who underwent bilateral cataract surgery at least 1 month previously with AcrySof IQ PanOptix or PanOptix Toric trifocal IOLs. This may also explain the widespread adoption and acceptance of this lens among surgeons in Europe and the US, where it has been most widely used. Right eye cataract surgery was done several years ago and went well. Pseudophakic negative dysphotopsia: Surgical management and new theory of etiology.

Cataract. Unlike other multifocal IOLs, Vivity IOL's non-diffractive proprietary technology reduces visual complications, giving the benefits of a monofocal IOL. The primary risk factor for developing either type of dysphotopsia is cataract surgery. MEDICAL PROFESSIONAL John C Hagan III, MD, FACS, FAAO It would be important to be sure that the IOL is stable and not dislocated or firmly anchored. Different tests used to measure contrast sensitivity across studies makes it hard to directly compare studies but regardless of test used, the PanOptix has performed comparably to other multifocal lenses and extended depth of focus lenses in regards to contrast sensitivity in photopic and mesopic conditions. PMID: 29502619. In this study, patients were eliminated if their residual refractive error in either eye deviated from plano by more than 0.5 D of sphere or 0.75 D of cylinder. Multifocal neuroadaptation: Can training help the brain? Negative dysphotopsia: long-term study and possible explanation for transient symptoms. Additionally, there may be a central nervous system component as well, as Masket et al reported 80% reduction in the ND scotoma when the contralateral eye is occluded. Pharmacologic miosis with drops such as pilocarpine and brimonidine can help relieve PD, especially at nighttime, but does little for ND symptoms. The exact nature of these events is incompletely understood, but there are many different theories with both clinical and laboratory evidence to support them. [1] While no postoperative significance exists past day 1, optical modeling evaluation suggests the haptic junction illuminates the peripheral retina differently than the peripheral optic moving the illumination gap anteriorly. There was no statistically significant difference between the predetermined near distance of 40 cm (median 40.3 cm) and the individually preferred reading distance (median 39.5 cm) both for uncorrected ( p = 0.21) and distance-corrected ( p = 0.92) testing and no significant changes were observed for reading acuity, letter size and reading speed. Number 3099067. This may have explained the very low percentages (<5%) who were dissatisfied with any of the premium lenses evaluated. Positive dysphotopsia is unwanted light, such as a streak, starburst, flicker, fog or haze, and negative dysphotopsia is a black line or crescent in the far periphery of patients' vision," explains Jack Holladay, MD, MSEE, FACS, who lives in Bellaire, Texas. First version of the Morcher 90S anti-dysphotopic IOL. Halo propensity was also studied in the aforementioned optical bench performance study comparing the PanOptix to the multifocal ReSTOR +3.0 D IOL by Lee et al[4]. Sharp-edged intraocular lens design as a cause of permanent glare. Haptics of certain lenses may become fibrosed or start eroding through the edge of the capsule into the sulcus, even several weeks post-surgery.25 Intraocular lenses may also develop a strong adherence to the capsule, making it difficult for the surgeon to dissect it from the capsular bag.26 If IOL exchange is done soon enough after the initial cataract extraction, the surgeon may use the original clear corneal incision.25 Note that if an intraocular lens exchange is considered, YAG capsulotomy should be avoided, as the open posterior capsule requires a vitrectomy during the IOL exchange procedure.25, Some patients with severe negative dysphotopsias have found relief from IOL exchange with reverse optic capture, sulcus fixation and piggyback IOL insertion.20-22 YAG anterior capsulotomy has also been shown to help resolve symptoms of negative dysphotopsias.23,24. In most cases they diminish with time, but some patients have severe long-term symptoms. There is currently no agreed-upon management strategy for positive dysphotopsia symptoms.

Patient-reported outcomes of multifocal and accommodating intraocular lenses: analysis of 117 patients 2–10 years after surgery. Bulk reprints for the pharmaceutical industry. Incidence of positive dysphotopsia is way higher than 1.5% of patients. Hawker MJ, Madge SN, Baddeley PA, Perry SR. Refractive expectations of patients having cataract surgery. 26. 2013;39:1110-5. Kershner RM. Thinner implants being particularly susceptible to the relatively limited forces generated by the capsule's contraction. They have one focal point and can improve sight at one distance: far or near. Refractive Surgery Complex Case Management. "Dysphotopsia just means an unwanted image that patients see after cataract surgery. Although not statistically significant, patients reported higher rates of overall satisfaction with the PanOptix over both ReSTOR lenses. The first trifocal IOL was recently approved by the FDA for use in the United States. Patient perspectives of cataract surgery: protocol and baseline findings of a cohort study. Investigators speculate that positive dysphotopsias are caused by stray light projecting onto the retina, which worsens if that stray light is concentrated in one particular area. Five-year study. doi:10.1038/eye.2015.147, 4. ASCRS•ASOA Sympsium & Congress; 2015; San Diego, CA. 1. Left eye done several weeks ago and my vision is terrible. 2000;26:198-213.
