Guell et al reported improvement in BSCVA and mean postoperative spherical equivalent of -1.50D after clear lens extraction14.
In the vitrectomized group, BSCVA improved from 1.15 [+ or -] 0.60 preoperatively to 0.37 [+ or -] 0.19 at 1 month, 0.28 [+ or -] 0.15 at 3 months, and 0.16 [+ or -] 0.15 at 6 months.
These lenses are known to improve vision by one to two lines of best corrected visual acuity (BSCVA).
Best-corrected visual acuity with a contact lens was included in this analysis because the evaluation of visual acuity was limited to BSCVA or UCVA in most previous trials.
In the study of Namperumalsamy et al, (10) with a baseline BSCVA of 20/40 (6/12) to 20/400 (6/60) showed a trend toward a 2-line improvement in visual acuity with voriconazole.
The BSCVA (log MAR) improved significantly from 0.99 [+ or -] 0.57 preoperatively to 0.01 [+ or -] 0.07 at 6 months postoperatively (p = 0.001).
Group A: 1 month postoperatively, the BSCVA was 0.631+/-0.199 (range 0.02 to 1.0 i.e.
In the study of Carlos A et al (6) preoperatively, the spherical equivalent (SE) was -5.61 +/- 1.72 D, the cylinder was -1.78 +/- 1.24 D, and the best spectacle-corrected visual acuity (BSCVA) was 0.77 +/- 0.19.
Table 2 shows the outcomes of BSCVA, ECD, pachymetry, and straylight for each visit; the former two outcomes of which are also visualized in Figures 1 and 2 (BSCVA and ECD, resp.).
Data from the medical records included demographics, medical history, preoperative and postoperative best spectacle-corrected visual acuity (BSCVA) measured using the Snellen visual acuity (VA) chart, outcome and complications of surgery, results of accessory examinations (microbial tests), postoperative intraocular pressure, graft rejection, and other comorbidities and complications.
The main outcome measures were best spectacle-corrected visual acuity (BSCVA) and chronic ocular complications at the final follow-up.
The following data were recorded and assessed: patient demographics; ocular and familial history; preoperative data including best spectacle-corrected visual acuity (BSCVA), manifest refraction, pachymetry and topography; and perioperative and postoperative data including ablation depth, RSB (calculated), number of enhancement procedures, and the time from PRK until the appearance of ectasia.
