Purpose: Evaluate objective and subjective visual quality in eyes having
accommodative intraocular lens (Acc IOL) implantation (Crystalens HD,
Bausch and Lomb) after previous myopic laser in situ keratomileusis (LASIK).
Methods: Measure uncorrected distance, intermediate and near visual acuities
(UCDVA, UCIVA, UCNVA), best-corrected distance visual acuity, best-distance
corrected intermediate and near visual acuity (BCDVA, DCIVA, DCNVA),
deviation from target refraction, and ability to perform near and intermediate
visual tasks.
Results: The study comprised 9 eyes (8 patients; 4 men). The mean IOL power
was 19.08 +/- 1.45 dioptres (D). Mean BCDVA, DCIVA and DCNVA at month
3 were 1.02 +/- 0.11, 0.88 +/- 0.24 and 0.64 +/- 0.22 (M-notation) [c.f. J3]. 7
(78%) eyes gained BCDVA and no eyes lost BCDVA. 8 (89%) eyes achieved
DCNVA J3 or better at month 1. Manifest refraction spherical equivalent at
month 3 was -1.25 +/- 1.27 D (c.f. pre-operative target -0.73 D). Most patients
reported no or little difficulty in carrying out near and intermediate visual tasks,
with 5 (62.5%) patients reported ‘moderate or above› level of satisfaction.
Conclusion: Implantation of accommodative IOL in patients with myopic LASIK
provides good distance, intermediate and reasonable near visual acuities, with
predictable refractive outcome.

Purpose: To compare postoperative refractive errors due to calculation of axial
length using partial aoherence laser interferometry and A-scan ultrasound
(A-mode) for combined vitreous and cataract surgery.
Method: The study indicate 82 eyes of 65 patients who underwent combined
vitreous and phacoemulsification, 7mm optical diameter acrylic foldable intra
ocular lens(IOL)?X-70®.? implantation .These surgeries were performed by
same surgeon. Axial length was measured by using partial aoherence laser
interferometry OA-1000TM and A-mode AL-3000 TM was used for cases that
can’t measured by OA-1000TM in case of vitreous hemorrhage. IOL power
was decided by SRK/T formula. The errors between the actual postoperative
refraction at 1 week,1 month,3 months and 6 months and predicted refractions.
Result: Postoperative refractive errors were -0.49±1.33D? -0.39±1.32D?-
0.25±1.09D?-0.27±1.05D (OA-1000TM) ,and -1.12±1.10D? -1.10±1.36D?-
1.00±1.43D?-0.84±1.33D(AL-3000 TM). Significant difference (P
