IOL

Both the Tecnis multifocal +2.75 D and +4.00 D IOLs had good visual results, but the +2.75 D IOL had a better range of vision across near, intermediate, and distance.

Aphakic eyes that have no or inadequate capsular support can pose a significant challenge to cataract surgeons. Careful attention to the preoperative considerations, appropriate intraocular lens choices, surgical techniques, and postoperative management can ensure optimal results.

Trifocal IOLs can provide good uncorrected vision at near, intermediate, and far. Outcomes in a series of 30 patients show that a toric version of a trifocal IOL (AT Lisa tri 939MP, Carl Zeiss Meditec) delivers those benefits for patients with > 1 D of corneal astigmatism.

Accommodating-disaccommodating IOLs are being developed that mimic the movement of the young crystalline lens through the use of “Zonular Capture Haptics” technology.

When it comes to their eyes, patients want the safest treatments, and they know the best technology available is a laser. The cataract patient demographic is changing, and patients today have active lifestyles that demand functional vision.

Multifocal IOLs offer the potential to reduce spectacle dependence, but outcomes vary depending on optical design. Optimizing success and satisfaction depends on careful patient selection, thorough counseling, and good surgical technique.

An approach is described for completing cortex removal and IOL implantation after intraoperative 180° zonular dialysis.

IOL implantation was associated with more inflammation and slightly more visual obscuration in 120 children age 2 or younger undergoing bilateral cataract surgery. However, the rate of glaucoma was similar compared with an aphakic group.

When the topic of IOL implantation is on the table, the age of the patient does make a difference, according to pediatric expert Courtney Kraus, MD, who spoke at the Wilmer Eye Institute’s 27th annual Current Concepts in Ophthalmology conference.

Two clinicians explore why an optimal visual solution for patients may be using both a low-add multifocal and an extended-range-of-vision lens.

Phakic IOLs are viable alternatives for treating high refractive errors.

Implantation of the newest Implantable Collamer Lens phakic intraocular lenses (V4b and V4c) did not cause cataract formation in highly myopic patients.

Intraocular lenses have come a long way in the 66 years since Harold Ridley first inserted one, said Alan Carlson, MD, professor of ophthalmology, Duke University, Durham, NC.

While the accuracy of IOL power selection has advanced since the early days of phacoemulsification, the selection of the proper IOL power is always in the background when a surgeon performs cataract surgery, Dr. Hill said.

A new image-guided system streamlines surgical planning for patients undergoing cataract surgery with implantation of a single-piece aspheric IOL or a multifocal IOL.

Ophthalmologists spend significant amounts of time during cataract surgery trying to precisely center an implanted IOL to achieve the best possible vision after surgery. The high success rate of cataract surgery suggests that in most cases, they succeed.

Were he alive today, he would likely feel heartened by how his work has been carried on by Gerd U. Auffarth, MD, FEBO, who is now director of The David J Apple International Laboratory for Ocular Pathology at the University of Heidelberg, Germany.

The 2015 International Society of Refractive Surgery survey, the twentieth such survey and the seventh year published online, presents new findings about surgeons’ preferences in corneal and lens-based surgeries, premium intraocular lenses (IOLs), and femtosecond cataract surgery.

The glued IOL technique introduced by Amar Agarwal, MD, is an effective method for repositioning a dislocated 3-piece IOL in eyes without adequate capsular support, and it has advantages compared with suturing, according to Eric D. Donnenfeld, MD, founding partner, Ophthalmic Consultants of Long Island and Connecticut, Garden City, NY.

While 2015 may not have been the year for ground-breaking introductions or trials in the field of refractive surgery, plenty of improvements have kept the procedure an evolving process, Ophthalmology Times editorial advisory board members said.

A new non-apodized diffractive trifocal IOL allows 88% energy utilization and sends energy to near (40 cm), a preferred intermediate distance (60 cm), and far (infinity). Early results for visual acuity, contrast sensitivity, and photopic symptoms are encouraging.

Implantation of a silicone oil-filled accommodating IOL (FluidVision, PowerVision) provides 3 to 4 D of accommodation along with excellent distance, intermediate, and near vision-all of which remain stable during follow-up to 2 years, said Louis D. Nichamin, MD.

Take-home message: A novel approach to scleral suture fixation of a rotated in-the-bag toric IOL stabilizes the implant at the desired axis and prevents rotation in both clockwise and counterclockwise directions.

Intraoperative aberrometry aphakic and pseudophakic readings can be comparable with careful control of surgical variables. Both readings can be useful to predict postoperative manifest refraction.

This article presents recent epidemiological findings outlining the association between cataract surgery, potential visual acuity gains, glaucoma and the risk of undergoing additional general anaesthesia in under 2s. The authors of the original study concluded that use of IOLs in cataract surgery in young children should be critically reassessed, particularly in settings/communities where close, long-term follow-up is challenging.
