Phacoemulsification and Vitrectomy with the Erbium: or Neodymium:YAG-Laser
2002
Summary There are an increasing number of applications for Erbium:YAG and Neodymium:YAG lasers in opthalmology. Laser phacoemulsification and Erbium-laser vitrectomy are of major interest. We report the underlying technology and more than 1-year-experience using the PHACOLASE (Carl Zeiss Meditec, Jena, Germany, 10–100 Hz frequency, 5–50 mJ single pulse energy) for phacoemulsification and pars plana vitrectomy and the Lyla-Dodick laser photolysis (A.R.C. Laser, Eckental-Forth, Germany, 1–20 Hz, up to 8 mJ single pulse energy). The Erbium:YAG laser and Neodymium:YAG laser enabled us to extract lenses with up to medium hard nuclei. Moreover, the Erbium laser enabled fast vitrectomy with little…
Trifocal toric intraocular lenses in eyes with low amount of corneal astigmatism.
2020
Aim To evaluate the refractive and visual outcomes following cataract surgery and implantation of a trifocal toric intraocular lens (IOL) in eyes with low degrees of corneal astigmatism. Methods Twenty-six eyes of 22 patients who underwent implantation a trifocal toric IOL (FineVision PODFT, PhysIOL s.a., Liege, Belgium) were enrolled. Phacoemulsification with femtosecond laser, capsular tension ring insertion and intraoperative aberrometry were performed in all cases. All IOLs used showed a cylinder power of 1.00 D. Main outcome measures were refractive error and corrected-distance visual acuity (CDVA) and uncorrected-distance visual acuity (UDVA) values. Eyes were evaluated at 4mo post-su…
Intravitreal dexamethasone implant versus anti-vascular endothelial growth factor therapy combined with cataract surgery in patients with diabetic ma…
2021
Objective: to compare outcomes of cataract surgery combined with either anti-Vascular Endothelial Growth Factor (anti-VEGF) therapy or dexamethasone implant (DEX) in patients with diabetic macular oedema (DMO). Methods: Pubmed and Embase databases were searched for studies reporting outcomes of diabetic cataract surgery combined with either anti-VEGF or DEX, with a follow-up ≥3 months. The primary outcome was the mean change in central macular thickness (CMT). Mean change in best corrected visual acuity (BCVA) was considered as a secondary outcome. The mean difference between baseline and post-treatment values (MD) with 95%-Confidence Interval (95%CI) was calculated and meta-analyses were p…
Kosteneffektivitätsanalyse der Versorgung von Kataraktpatienten mit monofokalen Intraokularlinsen aus Sicht der Leistungserstatter
2003
BACKGROUND Data on the cost effectiveness of cataract surgery with respect to the German statutory health insurance system are hardly available. Hence the increase in visual acuity as primary efficacy endpoint, order of posterior capsule opacification as primary complication endpoint and direct cost for supplementation with monofocal intraocular lenses have been assessed via meta-analyses to evaluate the procedure's cost effectiveness from the perspective of the German statutory health insurance system. MATERIAL AND METHODS Using the medical internet database MEDLINE two meta-analyses on publications between 1995 and 2002 were carried out, one estimating the gained increase in visual acuity…
Objective and subjective evaluation of photic phenomena after monofocal and multifocal intraocular lens implantation11The authors have no commercial …
1999
Abstract Objective To objectively measure and compare halo, flicker, and glare disability in pseudophakic eyes with monofocal (MONO) and multifocal (MULTI) intraocular lenses (IOLs) with respect to the influence of corneal surface quality, astigmatism, and age. Design Prospective case series. Participants This clinical trial involved 28 eyes of 28 patients after small-incision cataract surgery with a MONO silicone IOL and 28 eyes of 28 patients with zonal-progressive silicone IOL. Intervention A computer program objectively determined halo, glare, and flicker. Corneal surface quality and astigmatism were measured using computerized videokeratography. Ray-tracing analysis was performed based…
Acu priekšējās kameras stāvoklis pacientiem pirms un pēc intraokulārās lēcas implantācijas
2016
Ievads: Priekšējā kamera ir ļoti svarīga acs struktūra, kas ir pildīta ar intraokulāro šķidrumu (IOŠ), kas cirkulē caur priekšējo kameras kaktu uz drenāžas kanāliem. Šīm struktūrām ir nopietna loma glaukomas attīstības patoģenēzē. Nepieciešams noskaidrot kā viena no visbiežākajām ķirurģiskajām manipulācijām (kataraktas operācija) ietekmē priekšējās kameras parametrus. Pētījuma mērķis bija izvērtēt izmaiņas acs priekšējās kameras parametros pēc fakoemulsifikācijas un inrtaokulārās lēcas (IOL) implantācijas, izmantojot Pentacam (Oculus, Wetzlar, Germany). Metodes un materiāli: Tika veikts prospektīvs pētījums. Pētījumā piedalījās 18 pacienti (20 acis), kuriem tika izvērtēts un salīdzināts acs…

Presbiopijas korekcija ar multifokālajām intraokulārajām lēcām
2017
Bakalaura darbs ir uzrakstīts angļu valodā uz 47 lapaspusēm. Tas satur 3 zīmējumus, 20 tabulas, 39 literatūras avotus un pielikumu. Darba mērķis ir salīdzināt divu jaunu intraokulāro lēcu (difraktīvā trifokālā lēca un paplašināta fokusa dziļuma multifokālā lēca) efektivitāti presbiopija korekcijā pēc kataraktas operācijas. Pētījumi tika veikti 3 mēnešu periodā pēc kataraktas operācijas, kad tika novērtēta redzes kvalitāte, mērot redzes asumu un kontrasta redzi fotopiskos gaismas un mezopiskos krēslas apstākļos. Abi introokulāro lēcu veidi nodrošināja lielisku redzes asumu visos skata attālumos un pilnu neatkarību no brillēm. Taču kontrasta jūtība un redzes asums mezopiskos krēslas apstākļos…
Day surgery for cataract: descriptive survey in central and southern Italy
2005
Abstract Day surgery has rapidly gained worldwide acceptance especially in the field of ophthalmology. In Italy, cataract surgery is the most frequently performed surgical procedure, even on account of the ageing of the population. This procedure represents a very sensitive indicator of trends in day surgery hospitalizations and of political-managerial situations in the different regional healthcare realities. The aim of this study was to evaluate the diffusion of cataract day surgery in ophthalmology centres/divisions in central and southern Italy in 2003. A questionnaire was used to collect information regarding the number of surgical procedures performed, types of hospital admissions, ti…
A new trifocal corneal inlay for presbyopia
2021
[EN] Corneal inlays (CIs) are the most recent surgical procedure for the treatment of presbyopia in patients who want complete independence from the use of glasses or contact lenses. Although refractive surgery in presbyopic patients is mostly performed in combination with cataract surgery, when the implantation of an intraocular lens is not necessary, the option of CIs has the advantage of being minimally invasive. Current designs of CIs are, either: small aperture devices, or refractive devices, however, both methods do not have good performance simultaneously at intermediate and near distances in eyes that are unable to accommodate. In the present study, we propose the first design of a …
