2.  Cataract is a recognized complication of all types of retinitis
pigmentosa especially posterior sub-capsular lens opacity
which occurs at a relatively younger age, which may be
combined with a restricted visual field causing significant visual
disturbance.
 Glare is a major symptom and the patient may require surgery at
a younger age.

3.  Apart from the general risks of cataract surgery, there are
specific additional risk factors2 that may result in
decreased visual outcome after cataract extraction in the
presence of RP namely,
 1. The zonules are usually fragile in RP.
 2. Posterior capsular opacificaton and anterior capsular
contraction are more aggressive in the presence of RP.

4.  To study visual outcome after cataract surgery in retinitis
pigmentosa(RP) patients
 To study relation of visual outcome with
-age of the patient,
-type of cataract,
-type of cataract surgery done.

5. We retrospectively reviewed the database in a standard
pretested format of consecutive series of 52 eyes with
RP who underwent cataract surgery. The changes in
visual outcome were measured and data analysed by
SPSS 23.

6.  The preoperative BCVA was < 6/ 60 in 94% of patients. The
BCVA improved after cataract surgery from ≥6/18 in 45.2%
(P < 0.001). But final BCVA did not improve in 28 eyes
(53.8%).
 The preoperative & final BCVA were significantly
correlated; final BCVA improved in the less advanced RP
group .

7.  The final BCVA was statistically not related to age
(P<0.096), type of cataract (P<0.691), age at which
cataract surgery done (P<0.015) or gender
(P<0.317). 3.8% patients have secondary glaucoma.

12.  Final BCVA is improved in approximately half of the
eyes after cataract surgery in patients with retinitis
pigmentosa.
 Final BCVA was better after phaco+IOL as compared
to after SICS+IOL.
