UPDATE 13 by Liz Hillman EyeWorld Staff Writer Biosyntrx, an ocular nutritional supplement company, wrote that Dr. Honan was close with Richard Kratz, MD (1920–2015), and Thomas Mazzocco, MD, stating they were "warmly known as the Three Amigos." "They were as curious and passionate about full body disease prevention as they were about the surgical practice of ophthalmology," Biosyntrx wrote of the trio. "Their intellectual curiosity about a vast number of subjects, including fo- cused patient care, fly fishing, wine making, and chocolate, never failed to charm and energize most any audience. A very close friendship like theirs seemed special among professional men." According to Biosyntrx, Dr. Honan, in addition to ophthalmol- ogy, was interested in nutrition science. The company stated that he consumed higher than recom- mended levels of vitamin C and credited his "flawless skin" to this practice. According to his own web- site, Dr. Honan used a non-medical, non-surgical allergy treatment called Nambudripad's Allergy Elimination Technique, both for his own aller- gies and in his practice. Dr. Honan held a professorship within Indiana University School of Medicine's Department of Oph- thalmology. He was selected by ASCRS as an Honored Guest for the 2010 ASCRS•ASOA Symposium & Congress. The Indiana Academy of Ophthalmology presented him with its Lifetime Achievement Award in 2016. In addition to ASCRS, Dr. Honan was a member of the Amer- ican Academy of Ophthalmology, the Indiana State Medical Associa- tion, and the Indiana Academy of Ophthalmology, where he served as president for a year. Dr. Honan was preceded in death by his wife, Kathleen Kouns Honan, to whom he was married for 73 years. He is survived by his sister Martha Ann Parr, his daugh- ters Linda (Jon) Silverberg and Susan (David) Jones, his son David, and his grandchildren and great-grandchild. "Dr. Honan was a long-time member of ASCRS and a good friend and mentor to many," Dr. Thornton said. "He will be sorely missed." EW L ong-time member of ASCRS, Paul Honan, MD, Leba- non, Indiana, died on May 18, 2017. Dr. Honan, born May 29, 1921, was an early adopter of IOLs and inventor of a device to prevent vitreous loss during cataract surgery. Even at 95 years old, just shy of 96, Dr. Honan actively practiced until a few days before his death. According to Dr. Honan's obituary in the Lebanon Reporter, he was a 1946 graduate of Hahnemann Medical College, Philadelphia, and opened a general medicine practice in 1948. Dr. Honan closed this prac- tice during the Korean War to serve in the U.S. Army from 1953–55. Spencer Thornton, MD, Nashville, Tennessee, a friend of Dr. Honan's, said Dr. Honan decid- ed to specialize in ophthalmology after his time in the eye clinic at Madigan Army Hospital in Tacoma, Washington. Dr. Honan completed his residency at Indiana University School of Medicine, Indianapolis, and opened a practice in his home- town of Lebanon, practicing there until May 12, 2017. According to Dr. Thornton, Dr. Honan performed one of the first, if not the first, IOL implantations in the state of Indiana in 1975, after he took a course by Cornelius Bink- horst, MD. Dr. Honan is known for developing the Honan Intraocular Pressure Reducer, or the Honan bal- loon, which Dr. Thornton said soft- ens the eye before cataract surgery. According to the Lebanon Report- er, Dr. Honan was also interested in contact lenses, at one point serving as president of the Contact Lens Association of Ophthalmologists. Remembering Paul Honan, MD Paul Honan, MD In the journal Shift in progression rate of keratoconus before and after epithelium-off accelerated corneal collagen crosslinking Yu Meng Wang, MMed, Tommy Chan, FRCS, Marco Yu, PhD, Vishal Jhanji, MD In this prospective case series, investigators considered how accelerat- ed epithelium-off corneal collagen crosslinking affected keratoconus progression. They determined that in the 47 eyes included here, the progression rate for anterior keratometry was significantly reduced from 0.063 D to –0.022 D. Posterior average keratometry went from –0.011 D to 0.0 D. Investigators determined that when it came to the progression rate of anterior average K after crosslinking, baseline anterior average keratometry was the strongest predictor of change. They also found that postoperative progression of anterior and posterior average keratome- try had a significant association with preoperative progression rate of posterior best fit sphere. Investigators concluded that after accelerated epithelium-off crosslinking, average keratometry progression rate was significantly reduced. This was found to be connected to posterior best fit sphere rate of preoperative progression and baseline anterior average keratometry. Cyclorotation during femtosecond laser-assisted cataract surgery measured using iris registration Chad Hummel, MD, Vasilios Diakonis, MD, Neel Desai, MD, Allen Arana, AS, Robert Weinstock, MD What effect does cyclorotation have on eyes that have undergone fem- tosecond laser-assisted cataract surgery together with iris registration? In this retrospective case series of 337 eyes, there was a statistically signif- icant mean cyclorotation of 5.81 degrees found postoperatively, as deter- mined using iris registration. In 67.4% of cases this was incyclorotation versus excyclorotation, which occurred in just 30.9% of cases. Likewise, in 47.37% of bilateral cases, incyclorotation was found, something that was reported as the most common occurrence. Investigators concluded that use of femtosecond laser-assisted cataract surgery may result in clin- ically significant cyclotorsion, which may impact outcomes of astigma- tism correction. In cases where there will be corneal or intraocular lens- based astigmatism correction in which practitioners need to determine cyclorotation, iris registration can be a helpful means. Evaluation of the percent tissue altered as a risk factor for developing post-laser in situ keratomileusis ectasia Alain Saad, MD, Perry Binder, MD, Damien Gatinel, MD The aim in this retrospective study of 593 LASIK eyes was to determine whether considering the current recommended amount of percent tissue altered (PTA) enabled practitioners to predict postoperative ectasia cases. Those included were taken from one surgeon's LASIK database. Each had normal preoperative topography, with a minimum of 2 years of follow-up, as well as sufficient data to determine PTA. Investigators determined that 21% had a mean PTA of 44. There was 304.4-micron mean residual flap thickness, with a mean attempted laser ablation of 79.8 microns. At a 30-month mean follow-up, none of the eyes devel- oped ectasia. Investigators concluded that with the current PTA calcu- lation, ectasia risk is not predicted for those with normal preoperative topography who had ultrasonically measured flap thickness. July 2017
