Refractive and Anterior Chamber Parameteric Changes After Nd:
YAG Laser Capsulotomy

Purpose: To quantify changes in anterior chamber parameters (depth, volume
and angle) and refraction after YAG Laser Capsulotomy.
Methods: In a prospective study 30 pseudophakic eyes of 27 patients with
uncomplicated phacoemulcification and 1-piece acrylic IOL were included.
Anterior chamber depth (ACD), anterior chamber volume (ACV) and anterior
chamber angle (ACA) measured by Pentacam rotating sheimpflug camera as
well as refraction compared before and one month after planned capsulotomy
with 4×4 mm opening diameter.
Results: Mean spherical equivalent refraction changed from – 0.51 ± 1.29 D to
-1.00 ± 1.49 D one month after treatment. The difference was significant (P:
0.042). ACD decreased significantly after laser therapy. (3.89±0.80mm) vs.
(4.48±0.64mm) (P: 0.001). ACV decreased after treatment, but this reduction
was not significant (P: 0.114). (188.06±52.22) vs. (174.73±43.44). ACA
deepened after laser treatment, but this increase in angle degree was not
significant. (P: 0.050) (38.61±10.24 º) before and (42.56±6.75º) after.
Conclusion: YAG laser capsulotomy after cataract surgery can induce
significant changes in AC depth and refraction; therefore spectacle changes
should be considered accordingly.

Study of the Feasibility and Vision Quality After Relatively
Personalized Implantation of Aspheric Intraocular Lens
Hui Song, Xin Tang
1. Tianjin Eye Hospital
Aim: To determine the prevalence and pattern of ocular manifestations in acute
leukemia in children.
Methods: All 47 cases of acute leukemia admitted to the Oncology center at a
tertiary hospital in eastern India from July 2007 to December 2009 underwent
detailed ophthalmic evaluation after peripheral blood smear diagnosis, before
and after chemotherapy.
Results: Ocular manifestations were present in 19 cases (40.4%). The type of
ocular finding were proptosis 6 cases (12.8%), retinal vascular changes 11
cases (23.4%), neuro-ophthalmic signs in 5 cases (10.6%) and hypopyon one
case (2.1%). Ocular findings were 37.7% with myeloid leukemia and 42.4%
with lymphoblastic leukemia .The age of presentation varied from 3 months to
15 years. Male to female ratio was 2.3:1 .The initial presentation had fever in
22 cases (46.8%) and visual complains 7 cases (14.9%). All patients received
chemotherapy and 5 cases radiation therapy. 9 cases (47.3%) had ocular
improvement post-chemotherapy.
Conclusion: High prevalence of asymptomatic ocular lesions in acute leukemia
necessitates routine ophthalmic examination to be included at the time of
diagnosis.

Multifocal IOL and Laser ASA Combination for Radial Keratotomy-
Cataract: Reversing the Past
Gulani Arun (1)

Purpose: To report efficacy and visual outcomes of ReStor multifocal IOLs
combined with Laser ASA in patients with previous RK surgery presenting with
cataracts.
Methods: 7 eyes with previous RK surgery underwent ReStor IOL implant for
correction of Cataract, hyperopia and presbyopia followed by Stage II- Excimer
ASA (Advanced Surface Ablation) to correct the astigmatism, irregular anterior
surface contour and effective optical zone.
Results: 7 out of 7 eyes underwent the planned stage of Laser ASA surgery.
100% of patients experienced improvement in unaided vision to 20/25 OU
for distance and 20/25 for near. They all noted improved night time glare and
driving confidence. This result has been stable with a follow range of 1-5 years.
Conclusions: With a resurgence of patients having undergone previous radial
keratotomy (RK) presenting for cataracts, we need to be ready for what could
be a refractive epidemic of patients having undergone previous refractive
surgery who are now looking for surgical options to restore their independence
with excellent, unaided vision for distance and near once again.

Purpose: To compare the visual performance obtained with two different
models of a new rotational asymmetric multifocal IOL.
Methods: 43 consecutive eyes of 26 cataract patients (age range 55-83 years)
were divided into two groups: group A, 22 eyes implanted with the Lentis Mplus
LS-312 MF15 IOL (Oculentis); group B, 21 eyes implanted with the Lentis
Mplus LS-312 MF30 IOL (Oculentis). Distance, near, intermediate visual acuity
outcomes, contrast sensitivity, patient satisfaction, ocular optical quality and
defocus curve were analyzed during a 6-month follow-up.
Results: A significant improvement in the uncorrected and corrected distance
visual acuities as well as in corrected near visual acuity was observed in
both groups after surgery (p≤0.01). A significant better uncorrected and
distance-corrected near visual acuity were found in group B (p≤0.01). UIVA
was significantly better for group A (p=0.01) at 3 months, postoperatively. In the
defocus curve, significant differences were present between groups for several
levels of defocus. No significant differences were present in postoperative
contrast sensitivity, patient satisfaction, optical quality and ocular aberrometry
among groups (p≥0.07).
Conclusions: Lentis Mplus LS-312 MF30 and MF15 IOLs are able to restore
the distance vision, with also a complete near visual rehabilitation with the
MF30 model.
