Acry-sof IQ ReSTOR multifocal TORIC IOL

Acry-sof IQ ReSTOR multifocal TORIC IOL





















有10%的人散光＞-2.0
裝多焦點人工水晶體注意-3.0的病人
注意散光是Regular or irregular?
Topography每個病人都要做，再做A –scan前, 而且要趁角膜很好的時候先做。
如果Topography與電腦驗光K readings不合？是不規則？tear film？corneal  scar？。 就不放toric IOL了！
裝 Restor IOL有65%有glare or halo vision，但65%沒關係
IQ遠100，中0近0
Restor IOL遠80，中8o近8O，biIateral植入會更佳

NTG,的risk factor:female,migraine headache, disc hemorrhage
Set target pressure:也要考慮角膜厚度！
用薬：用效果好的，注意：CME，uveitis，herpes，sulfa drug過敏
Dry eye :注意meibomian gland的功能
多焦CL：看遠可以，光線要良好
，或只有單眼開白內障。

dominant看遠，non-dominant看近
提醒病人是多看到了什麼，而不是看不到什麼。


tear film breakup time対乾眼症的診斷比Schirmer test較準，視力會fluctuation也是乾眼症的症狀

Reducing pre-existing corneal astigmatism

圖片
by Vanessa Caceres EyeWorld Contributing Editor   Refractive editor's corner of the world In this month's inaugural refractive corner, I'd like to give some food for thought on the topic of astigmatism. Astigmatism is one of the most common conditions a cataract and refractive surgeon deals with. It's more common than dry eye and even more common than blepharitis. In fact, more than 70% of the adult population has more than 0.5 D of pre-existing astigmatism. Interestingly, our incidence of correcting pre-existing astigmatism varies by procedure. With laser vision correction (LASIK, PRK, LASEK), we correct any amount of astigmatism 100% of the time. If it's there, it's addressed. Why? To provide patients the best opportunity to see without being dependent on glasses or contacts lenses. That's the mission of today's refractive surgeon. With cataract surgery, however, there is still a transition of traditional surgeons converting to refractiv

Managing multifocal IOL dysphotopsia

Pseudophakic dysphotopsia  Managing multifocal IOL dysphotopsia by Ellen Stodola EyeWorld Staff Writer  Patients may complain of an arc image, usually in one quadrant, that bothers them. It is usually described after many of the square-edge optic lenses are placed in the bag. The image is depicted by the drawing of the light rays hitting the square edge of the optic. Source: Doug Katsev, MD Dysphotopsias can be a potential problem after surgery, especially with multifocal IOLs O ne issue for patients receiving multifocal IOL implants is the potential for dysphotopsias, which can be bothersome and sometimes affect vision. Richard Tipperman, MD, Wills Eye Hospital, Philadelphia; John Berdahl, MD, Vance Thompson Vision, Sioux Falls, S.D.; Audrey Talley Rostov, MD, cornea, cataract, and refractive surgeon and partner, Northwest Eye Surgeons, Seattle; and Douglas Katsev, MD, Sansum Clinic, Santa Barbara, Calif., commented on dysphotopsias and how to address them

Impact of lens design and materials on cataract surgery

Impact of lens design and materials on cataract surgery by George H.H. Beiko, BM, BCh, FRCS(C) outcomes Analyzing the spectrum of light used for scotopic vision shows that blue light provides 35% of scotopic sensitivity. Source: George H.H. Beiko, BM, BCh, FRCS(C) Comparison of transmission of blue light in the natural crystalline lens and different current IOLs18 Source: George H.H. Beiko, BM, BCh, FRCS(C) S ynergy is the value and performance of any elements which, when combined, are greater than the sum of the separate individual parts. Achieving optical synergy in visual outcomes following cataract surgery is accomplished by selecting a high performance lens design produced with proven, high caliber materials. Proper lens selection has been shown to improve spherical aberration correction, chromatic aberration correction, light transmission, material clarity, as well as limit lens epitheli
