Edf Presbyopia Correction Iol Implanted During Cataract Surgery Offers Excellent Vision At All Distances

Patients who person a caller type of lens implanted successful their eyes during room for cataracts aliases to correct their eyesight person fantabulous aliases bully imagination complete distances some adjacent and far, and often nary longer request spectacles for reading.

Research presented coming (Sunday) astatine nan 43rd Congress of nan European Society of Cataract and Refractive Surgeons (ESCRS) evaluated outcomes for astir 200 patients successful 17 sites successful Europe and Asia-Pacific who had room to implant nan TECNIS PureSEETM, a purely refractive extended extent of section (EDF) presbyopia correction Intraocular Lens (IOL). Presbyopia is nan information that affects each group arsenic they age, making it harder to attraction intelligibly connected adjacent objects and text.

The study looked astatine ocular acuity aft surgery: really good nan patients could spot complete far, intermediate and adjacent distances connected nan logMAR ocular acuity charts utilized by ophthalmologists that dwell of rows of letters that go smaller arsenic they spell down nan chart. It besides measured Manifest Refraction Spherical Equivalent (MRSE) – a measurement of quantifying nan refractive errors of nan eye. In addition, nan study reported connected really patients were managing aft room successful position of whether aliases not they needed spectacles for reading, really satisfied they were pinch their outcomes and whether they would urge nan lens to others.

Data were disposable for 238 patients astatine nan clip of nan Congress, making it 1 of nan biggest studies to study connected this type of lens truthful far. The findings showed that nan EDF presbyopia correction IOL, connected average, provided fantabulous distance, very bully intermediate, and functional adjacent imagination without glasses, pinch small refractive error.

Nearly each patients (96%) reported needing glasses 'none' aliases 'a small of nan time' for region vision; 93% reported this for intermediate distances, 62% for adjacent distances, and 85% for wide vision. 

For restitution pinch nan outcomes, 96% were 'mostly' aliases 'completely' satisfied pinch their region vision, 94% pinch intermediate, 73% pinch near, and 95% pinch wide vision; 96% would urge nan lens to their family and friends.

Professor Oliver Findl, Chair of nan ESCRS Education Committee, is simply a advisor oculus surgeon and caput of nan ophthalmology section astatine Hanusch Hospital, Vienna. He presented nan findings to nan congress. 

He said: "The PureSee EDF IOL gave patients fantabulous distance, very bully intermediate and functional adjacent vision, which resulted successful precocious diligent restitution pinch little request for spectacles. The information successful this study came from respective surgical centres passim Europe and Asia successful a 'real world setting' extracurricular of nan accustomed objective trials. 

"The class of EDF IOLs, specified arsenic nan TECNIS PureSee, are a awesome replacement to multifocal lenses for patients who wish to beryllium little limited connected spectacles aft lens room and do not want to return nan consequence of unwanted optical side-effects."

Currently, erstwhile a personification requires cataract surgery, their cloudy lens is replaced pinch an artificial lens. To alteration a diligent to spot objects some adjacent and far, their surgeon whitethorn connection them a prime of lenses, specified as: 

1. Monofocal lens, which enables patients to spot intelligibly astatine 1 region constituent (far, intermediate aliases near), but which mean they request spectacles for nan distances they person not chosen. If room is needed connected some eyes, patients tin take to person a lens for close-up activity successful 1 eye, and different lens for distances successful nan different eye. This operation is known arsenic monovision and nan encephalon past adjusts to nan 2 distances truthful that nan diligent tin spot some adjacent and far.
2. Multifocal lens, which tin supply bully imagination complete each distances, without nan request for glasses. The lens is divided into different zones aliases concentric rings, pinch different medicine lengths for each section, which supply clear, complete imagination erstwhile combined. However, these lenses whitethorn origin immoderate unwanted optical side-effects, particularly astatine night.
3. Extended extent of section (EDF) lens, which provides bully region and intermediate (arm's length) vision, but spectacles whitethorn still beryllium needed for adjacent activity specified arsenic reference mini print.

The quality betwixt immoderate of these lenses and nan EDF presbyopia correction IOL that we utilized successful this study is that it is simply a afloat 'refractive' IOL, meaning it uses variations successful nan lens curvature to attraction ray astatine a azygous distance. The aboveground of nan lens is soft and you don't spot bumps aliases rings. This intends you person amended nighttime imagination and don't spot halos, starbursts, glare and different ocular disturbances that tin hap pinch different lenses."

Dr Joaquín Fernández is ESCRS Secretary, CEO of Qvision and Medical Director of Andalusian Ophthalmology Institute astatine Vithas Hospitals. He was not progressive successful nan research. He commented: "Eye room for cataracts aliases to correct imagination is perpetually evolving but, truthful far, nan 'holy grail' of processing a lens that tin springiness patients bully imagination complete each distances without immoderate ocular disturbances has been elusive. These information from a 'real world' study are very encouraging and propose that nan disposable options are expanding to amended meet nan expectations of our patients. However, different options still request to beryllium explored. We look guardant to further results from nan study."
