Ko. Karp et al., Outcomes of temporal clear cornea versus superior scleral tunnel phacoemulsification incisions in a university training program, OPHTHAL SUR, 32(3), 2001, pp. 228-232
BACKGROUND AND OBJECTIVES: To evaluate the complication and visual outcomes
of residents performing temporal clear cornea (TCC) compared to superior s
cleral tunnel (SST) phacoemulsification,
PATIENTS AND METHODS: We conducted a retrospective analysis of complication
s and visual outcomes for 534 phacoemulsification procedures done by third-
year residents over a five-year period (June 1992-July 1997) at the departm
ent of ophthalmology, University of Chicago. All cases were completed using
a TCC or SST incision.
RESULTS: There was vitreous loss in 6.0% of 348 eyes with TCC incisions and
in 11.8% of 186 eyes with SST incisions (P < 0,02), Posterior capsule brea
ks occurred in 11.5% of the TCC group versus 17.7% in the SST group (P < 0,
0453). Best corrected visual acuity of 20/40 or better was achieved in 82.5
% of all eyes with TCC incisions and in 75.3% of all eyes with SST incision
s (P < 0,05). When 151 patients with previous ophthalmic conditions were ex
cluded, the difference in BCVA between the two groups was not statistically
significant.
CONCLUSIONS: Most institutions train residents with the SST technique prior
to advancing to TCC. This study demonstrates that with proper teaching, re
sidents can achieve excellent outcomes using TCC incisions, and can therefo
re be trained in this technique concurrently with SST incisions.
