Objective/Purpose: To analyse 24 months results of the new rotatory
asymmetric bifocal IOL not depended on pupil size.
Methods: Oculentis Mplus IOLs were implanted in 25 patients after standard
phaco cataract surgery, 49 IOLs in total. UCVA at far, middle and near distance
(ETDRS charts for 6m, 100cm and 40cm) and contrast sensitivity (Pelli Robson
Contrast Sensitivity Test) were measured. Defocus curve was measured in 37
eyes.
Results: UCVA at far distance increased after 7 days from 0.34 to 1.08. UCVA
at near distance was 0.80. PRCST increased from 1.35 to 1.85. Halo and glare
light phenomenons observed 8 patients in the lower part of the light sources.
One patient has a disturbing effect during night driving. Three patients use
glasses for far distance (one myopic and 2 hyperopic shifts), 5 patients use
glasses for near distance but only for special conditions. In two eyes the
secondary cataract (proliferative form) was successfully removed one year
after surgery. All patients were satisfied with the new quality of vision.
Conclusion: New MF IOL has acceptable long term results without loss of
contrast sensitivity and disturbing light phenomenon.

Objective: This is a case report describing a case of Dirofilaria which presented
to us as conjunctivitis, treated elsewhere for the same. Reports from India are
limited. Dirofilarial ocular manifestations have been reported as early as 1885.
Case Report: A 55 year old lady from South India, reported to our Hospital with
foreign body sensation, pain and redness in the left eye since 3days.
On examination a diffuse conjunctival congestion was noted. A slit lamp
examination revealed a live motile worm in the temporal subconjunctival space.
Rest of the ocular examination was normal. Systemic examination revealed
no other nodules, no lymphadenopathy. Routine blood investigations were
normal, including eosinophil count. Blood smear was negative for microfilaria.
The live worm was removed under local anesthesia. It measured 12cm in
length, 0.45cm in diameter. Specimen was identified as Dirofilaria repens.
Conclusion: This case brings to our notice the possibility of the endimicity of
dirofilaria as evident from previous reports from the same area. Dirofilaria
because of its masquerading abilities, mimics a myriad of ocular diseases. The
prompt diagnosis and treatment resulted in a symptom free patient.

Purpose: To evaluate distribution of corneal biomechanical measurements
(Corneal Hysteresis = CH, Corneal Resistance Factor = CRF) in myopia and
myopic-astigmatism population.
Methods: 180 eyes with myopia and myopic-astigmatism candidated for laser
refractive surgery included in this study. Complete examination of anterior
and posterior segments, manifest refraction spherical equivalent (MRSE)
, OrbscanII and Zywave were performed preoperatively. Ocular Response
Analyzer was used to measure CH and CRF. Distribution of all corneal
biomechanical properties and correlation between these parameters and
MRSE, age and sex were determined.
Results: Mean age was 28 7 years. Mean MRSE was -4.21D. Mean CH and
CRF, was 10 mmHg and 10.16 mmHg , respectively.28.4% of all myopic
population had CH about 10mmHg, and CRF in 25.9% of myopic population
was 10mmHg.There was no statistically significant correlation between MRSE
& CH ( Rs= 0.001 , P= 0.71 ) and MRSE & CRF ( Rs= 0.01 , P= 0.18 ).
Conclusion: Our study demonstrated the distribution of corneal biomechanical
properties. In normal myopia and myopic - astigmatism population in IRAN,
and confirmed that, there was no statistically significant correlation between
corneal biomechanical properties and MRSE , age and sex.

Purpose: To report a rare case of sebaceous carcinoma of the caruncle.
Methods: A 50-year-old man developed a slowly enlarging mass in his left
caruncle. On the basis of the clinical findings, we suspected it to be a
papillomatous lesion. However malignancy could not be ruled out, so, total
wide excisional biopsy with frozen section control was undertaken and the
lesion was studied histopathologically.
Results: Histopathological examination disclosed infiltration of the caruncular
stroma by lobules of a malignant neoplasm that had prominent cytoplasmic
vacuoles, typical of well differentiated sebaceous carcinoma.
Conclusion: Although it is best known to arise in the meibomian glands of the
tarsus, sebaceous carcinoma can very rarely arise in the caruncle and can be
misinterpreted clinically and even histopathologically. This report suggests the
importance of considering sebaceous carcinoma in the differential diagnosis
of such benign looking lesions in this rare site. In our case we believe, early
detection and radical excision of the tumour may yield a better prognosis for
the patient.
