Refractive Surgery Outlook: 2011 Archives

Read the clinical news and journal updates from the 2011 issues of Refractive Surgery Outlook.

Outlook Features

October - December | IOL “Scaffold” Technique Helps Prevent Dropped Nucleus

When a posterior capsular rupture (PCR) occurs with vitreous prolapse and the nucleus still in the bag the stage is set for a possible nucleus drop. Most surgeons will respond by extending the corneal incision to deliver the nucleus. Read more »

September | The Mystery of Why Corneal CXL Works

Thanks to positive clinical outcomes and apparently minimal risks, corneal cross-linking (CXL) has transformed progressive keratoconus into a treatable condition for thousands of patients around the world. Even though ophthalmologists worldwide have embraced e CXL, both clinicians and ophthalmic researchers still don’t really know why it works. Read more »

July - August | Epi-On or Epi-Off? Only Time Will Tell

The search for ways to improve corneal collagen cross-linking (CXL) has ignited interest among corneal subspecialists in a fundamental dilemma: epithelium on or off? The notion that cross-linking might not require surgeons to remove the epithelium has been a common theme heard from the podium and during hallway discussions and dinnertime conversations at recent research meetings.

June | Three New Paradigms in Surgical Vision Correction

Clinical trial results for three new technologies suggest that each shows potential for addressing the visual problems of patients who largely have been left out of the refractive surgery revolution -- low myopes, low hyperopes and emmetropes in their early forties with presbyopia. Read more »

May | Does Increased IOP During Femtosecond LASIK Matter?

Since the early days of LASIK, some ophthalmologists have expressed concern about possible ocular damage from high intraocular pressure (IOP) when mechanical microkeratomes cut LASIK flaps. Today, this same issue is being raised with the femtosecond laser. Read more »

April | Meibomian Gland Dysfunction Gains New Attention

Ophthalmologists received a wake-up call from a distinguished panel of international experts on ocular surface diseases last month. In a consensus report developed over two years, the International Workshop on Meibomian Gland Dysfunction called on ophthalmic surgeons and clinicians to pay closer attention to this underdiagnosed, underappreciated and undertreated ocular disorder.

March | Who Will Pay for Femtosecond Cataract Surgery?

Femtosecond cataract surgery has generated a lot of excitement with its promise of safer, more precise surgery, as well as a fair share of resentment. But there's one thing most can agree on: The high cost of this high-tech laser may prevent it from gaining widespread adoption. Read more »

February | Wavefront-Optimized vs. Wavefront-Guided: Where We Stand Four Years Out

The introduction of wavefront-guided (WFG) refractive surgery in the United States with the Wavelight Allegretto Wave Eye-Q excimer laser system (Alcon) has presented surgeons who were already pleased with the Allegretto's wavefront-optimized (WFO) results with some dilemmas. Read more »

January | Early Results Suggest Combined CXL and PRK Can Improve Vision Quality in Early Keratoconus

Simultaneously treating certain cases of early keratoconus with corneal cross-linking and custom photorefractive keratectomy (PRK) ablation of less than 50 microns is a safe and effective way to improve visual quality in young adults while halting progression, a Saudi Arabian study has concluded.
