consultation section
cataract surgical problem, edited by Samuel Masket, MD
An active 78-year-old woman had seemingly uneventful cataract extraction with lens implantation using sub-Tenon’s anesthesia and an AcrySof lens in the bag through a superior limbal incision. Two days postoperatively, she had 2 small Nd:YAG laser capsulotomies in the posterior capsule near the edge of the optic to resolve capsule block and artificial myopia. A tonic pupil contributes to disabling glare and related phenomena postoperatively, and she cannot drive at night. The patient is intolerant of her current quality of vision and refuses a custom contact lens. Pilocarpine 0.5% induces miosis but does not adequately reduce her symptoms. How would you proceed?

Retreatment after initial laser in situ keratomileusis
W. Andrew Lyle, MD, George J.C. Jin, MD, PhD
Patients with both undercorrection and regression after initial LASIK can be safely and effectively retreated with LASIK.

Excimer laser retreatment of residual myopia following photoastigmatic refractive keratectomy for compound myopic astigmatism
Weldon W. Haw, MD, Edward E. Manche, MD
Retreatment following PARK resulted in a reduction of residual myopia with or without astigmatism with no decrease in contrast sensitivity. However, some eyes may experience significant regression associated with haze and loss of BSCVA.

Intraocular lens power calculations in patients with extreme myopia
Roberto Zaldivar, MD, Mitchell C. Shultz, MD, Jonathan M. Davidorf, MD, Jack T. Holladay, MD
In eyes with extreme myopia, using B-scan ultrasonography to measure the corneal vertex to foveal length is more accurate than using an A-scan and may enhance postoperative results.

Automated keratoconus detection using the EyeSys videokeratoscope
Philippe J. Chastang, MD, Vincent M. Borderie, MD, Santos Carvajal-Gonzalez, PhD, William Rostène, PhD, Laurent Laroche, MD
Clinically apparent keratoconus was detected among normal corneas and different irregular corneal shape patterns using the EyeSys System 2000 data. Sensitivity was 88.5% and specificity, 94.9% in the validation set.

Results of pediatric laser in situ keratomileusis
Amar Agarwal, MS, FRCS, FRCOphth, Athiya Agarwal, MD, Tahira Agarwal, DO, Azimuddin Azim Siraj, FRCS, MMed, DipNB, DO, Priya Narang, MS, Sameer Narang, MS, DO
Laser in situ keratomileusis offers promising results in select pediatric cases with anisometropia. In this study, 16 pediatric eyes were treated with LASIK and the results were encouraging.

Epithelial heating rates with topical ciprofloxacin, ofloxacin, and ofloxacin with artificial tears after photorefractive keratectomy
Ghanshyam M. Patel, MD, Alice Z. Chuang, PhD, Elena Kiang, MD, Narayan Ramesh, MD, Shrabanee Mirra, MD, Richard W. Yee, MD
Corneal epithelial healing and postoperative haze improved with topical ofloxacin and tear supplementation when compared with ciprofloxacin. Use of ofloxacin is recommended to improve healing and minimize complications after PRK.

Nonpenetrating filtration surgery for glaucoma: Control by surgery only
Elie Dahan, MD, MMed Ophth, Matthias U.H. Drusedau, FRCS
During a mean follow-up of 46 months, IOP control was achieved in 86 eyes with POAG by nonpenetrating filtration surgery without medication. After a mean of 29.9 months, 48 eyes required revision of the filtration site to maintain IOP below 21 mm Hg without medical therapy.

T-cut in the bottom of the scleral pocket in combined cataract and glaucoma surgery
Markus Rossmann, MD, Stefan Harrer, MD, Karl Rigal, MD
A prospective study comparing a T-shaped incision in the inner lamina of the phaco tunnel with phacotrabeculectomy showed the T-cut to be an efficacious and sparing technique for a triple glaucoma procedure.

Transforming growth factor- isoform proteins in cell and matrix deposits on intraocular lenses
Shizuya Saika, MD, Takeshi Miyamoto, MD, Yuka Okada, MD, PhD, Osamu Yamanaka, MD, Yoshitaka Ohnishi, MD, PhD, Akira Ooshima, MD, PhD
Transforming growth factor- was found on cells that adhered to implanted IOLs as well as the extracellular matrix that accumulated on the IOL surface. This TGF-bmay influence healing of residual lens capsules after cataract extraction with IOL implantation.

Double-masked prospective ocular safety study of a lens epithelial cell antibody to prevent posterior capsule opacification
William R. Meacock, FRCOphth, David J. Spalton, FRCP, FRCOphth, Emma J. Hollick, FRCOphth, James F. Boyce, PhD, Sarah Barman, PhD, Giorgia Sanguinetti
A randomized, placebo-control trial found that the immunotoxin MDX-RA is safe for intraocular use and may help prevent PCO.

Posterior capsule opacification after phacoemulsification: Foldable acrylic versus poly(methyl methacrylate) intraocular lenses
F. Hakan Oner, MD, Üzeyir Gunenc, MD, Sevgi Tongal Ferliel, MD
In addition to its optic material, the AcrySof IOL’s rectangular optic edges create straight angulation on the posterior capsule, helping to prevent PCO.

Endothelial cell loss after phacoemulsification: Relation to preoperative and intraoperative parameters
Tony Walkow, MD, Norbert Anders, MD, Sonja Klebe, MD
The location of corneoscleral incisions for phacoemulsification can be chosen according to the preoperative astigmatism without inducing additional adverse effects on the corneal endothelium.

Does preservative-free lignocaine 1% for hydrodissection reduce pain during phacoemulsification?
Jennifer H.Y. Tan, FRCS, Robert L. Burton, FRCOphth
Visual analog scoring showed that hydrodissection with lignocaine 1% compared with BSS does not lessen pain during phacoemulsification using topical anesthesia.

Effect of corneal thickness on the accuracy of intraocular pressure measurement in rabbits after excimer laser photoablation
Jason Stahl, MD, Steven Vold, MD
Intraocular pressure measurement accuracy of the Tono-Pen and pneumotonometer were not significantly altered after excimer laser photoablation of the rabbit cornea.
