(2.00-4.00 D), and high ( 4.00 D). Two common
surgeries to treat hyperopia are refractive lens
exchan…

Progressive Cataract, Elevated IOP, and Flat Anterior Chamber After PPV and Trabeculectomy
CASE PRESENTATION
A 45-year-old woman with type 1 diabetes presented
to a retinal specialist with a nonclearing vitreous hemorrhage
in her phakic left eye. The patient underwent an
uncomplicated pars plana vitrectomy (PPV), but her IO…
Getting the Most From Topography
In the early 1980s, keratorefractive surgery was developing
via a steady stream of incisional, excisional, and
onlay techniques that changed the cornea’s shape
and thus its curvature. It became clear that simply
measuring visual acuities and…
You Treated Me. How About My Son?

Improving LASIK’s and PRK’s Outcomes on Irregular Corneas
Most ophthalmologists are familiar with
computerized corneal topography maps
and have been using them diagnostically
in cataract and refractive surgery for nearly
2 decades. Because of the ease of assessing corneal
data in this format (vs num…
Refractive Corneal Surgery Without an Excimer Laser
Across the globe, laser vision correction superseded
incisional keratotomy as the dominant
form of corneal refractive surgery in the first half

eyes have undergone excimer laser vision correction …
Retropupillary IOL for Aphakia: Surgical Technique
Many techniques have been described for correcting
aphakia with inadequate capsular support.
The most common IOLs that are used
include anterior chamber, posterior chamber,
iris-fixated, and scleral-sutured IOLs; however, there is no
current …
Choosing an IOL After LASIK
The number of post-LASIK patients seeking cataract
surgery is on the rise, representing a challenge
as well as an opportunity. The combination
of challenging IOL calculations, imperfect
targeting of emmetropia, and very high expectations

Managing Vitreous Loss During Cataract Surgery
Because vitreous is virtually invisible, I recommend
using preservative-free triamcinolone acetate
(Triesence; Alcon) to enhance visualization during
anterior vitrectomy. Many surgeons still
use cellulose sponges for anterior vitrectomy and to…
IOL Selection and Power Calculations in Eyes After Retinal Surgery
Few patients are as exceptionally and immediately
grateful for successful cataract surgery as the post-vitreoretinal
surgery patient. For some of these
individuals, cataract surgery is the end of a path
that began with an epiretinal membrane o…
Patient-Reported Outcomes After LASIK
Patient-reported outcomes (PROs) are defined by
the FDA as “any report of the status of a patient’s
