Purpose: To demonstrate an effective technique to handle postoperative
occlusio pupillae after cataract surgery and removal of the underlying posterior
capsular plaque.
Methods: A case report of a 7 year old boy who had undergone cataract
surgery elsewhere followed by development of occlusio pupillae. Central iris
tissue covered over and adherent to the PCIOL was dissected and removed
using vitreoretinal scissors and forcep. Pupilloplasty was performed. Iris
retractors were used to stretch the pupil and view the underlying posterior
capsular plaque behind the PCIOL. Removal of the underlying posterior plaque
was done with the help of modified cystitome and vitreoretinal scissors through
the opening of previous iridectomy. This was followed by anterior vitrectomy
and removal of viscoelastics.
Results: The surgical technique resulted in a clear central visual axis. With
appropriate postoperative management and control of inflammation by
steroids; increased visual acuity was observed postoperatively.
Conclusions: Difficult situations can be tackled by meticulous surgical approach
and effective postoperative management.

Objective: To evaluate refractive results in patients with keratoconus after
cataract surgery.
Methods: Retrospective review of cases of patients with keratoconus after
phacoemulsification cataract surgery with complete eye exam, corneal
topography, anteroposterior axis and IOL calculation by immersion ultrasound.
Complications and refractive results were registered. Exclusion criteria:
Previous intraocular surgery, complications severely limiting postoperative VA.
Results: Ten eyes were included. Average age was 52.9 SD 11.49. Preoperative
VA CF 4 meters. Preoperative SE -14.23 D. Average K1 was 51.73 D, K2
was 50.10 D. Average Central Pachymetry 455.4 µ. The anteroposterior
axis average was 27.18 mm SD 2.81. Average IOL power was +2.05 D.
Postoperative BCVA 0.5, Postoperative SE -1.54 D. Corneal incision was
made at 80% of cases.
Conclusion: Refractive results of patients with keratoconus and cataract are
variable and patients should be warned of it.

Objective: This course is intended to give a detailed approach to a patient
presenting with ocular trauma causing lenticular damage and will deal with all
nuances of traumatic cataract management for surgeons practising in limited
resource settings to those in tertiary eye care centres.
Summary of Content: Ocular Trauma whether blunt or penetrating could result
in injury to the crystalline lens causing visual disturbances. Traumatic lens
opacification is a challenge as there may be associated ocular structure
damage. Thorough ocular examination and judicious use of investigative tools
to determine the nature and extent of damage helps in decision making. The
decision making will rest on key issues such as age of the patient, integrity of
the globe and the capsule and presence of intraocular foreign body. The timing
and technique of cataract surgery and primary or secondary lens implantation
will determine the results. Biometry in an injured eye and the type of lens and
its positioning with or without capsular support will also determine long term
visual results.
Target Audience: General Ophthalmologists
Education Level: Intermediate

HLO is a surgical emergency as engage the visual prognosis. The challenges
consist of therapeutic treatment of hypertension and the risk of corneal and
vitreous complications. The prognosis depends on the corneal and optic nerve
damage. The purpose of the study is to determine the epidemiological and
etiological cause of HLO and to propose treatment for each case.
Materials and
Methods: This is a retrospective study on 70 patients from January 2008 until
December 2010 collected in ophthalmology department of UHC 20Août of
Casablanca.
Result: bass visual acuity and ocular pain were present in 100% of cases,
followed by corneal edema in 89% of cases. The main cause of hypertension
was intumescent cataract. After introduction antiglaucoma medical treatment,
the patients underwent surgical treatment; the extracapsular cataract extraction
with implantation was performed in most cases.
Discussion: The lens may be responsible for hypertension through several
mechanisms. The diagnosis is purely clinical. After medical treatment, surgical
treatment is cataract extraction.
Conclusion: The original lens hypertension is a problem both in terms of
pathogenic than the therapeutic level. The diagnosis and understanding of
each alternative etiopathogenic is necessary for the surgery indication which
usually necessary to preserve the function of the affected eye.
