Purpose: To evaluate safety and efficacy of Toric ICL implanted to treat
ametropia in stable Keratoconic eyes after CXL.
Methods: The study included 24 cross linked keratoconic eyes. All eyes had
stable refraction over the past 6 monthly visits. Toric ICL was implanted to
correct the sphere and cylinder refractive error. All cases were followed up for
more than 24 months.
Results: Patients› mean age was 25.6 ± 4.1 yrs. (21 - 33 yrs.). Preoperative
subjective refraction was: Sph. -5.42 ± 4.45 D (0.00 to -14.50) & Cyl. -4.34 ±
1.62 D (-3.00 to -7.50). The BCVA: 0.63 ± 0.14 (0.4 - 0.8). Postoperative UCVA
0.88 ± 0.18 (0.6 to 1.2), 100% of cases gained one line or more. Mean vaulting
of the ICL after 18 months was 509 ± 141 µm. No single major complication
was reported.
Conclusion: Toric ICL is safe and efficient in refractive correction of Keratoconus
after stabilizing the condition by CXL. Subjective refraction is the dependable
one for ICL power calculation.

Purpose: To compare the effect of LASIK on contrast sensitivity one week and
one month after by femtosecond and mechanical keratomeSBK.
Methods: 15 patients (thirty eyes) were enrolled into each group- femtosecond
LASIK and mechanical keratome SBK. Pre-LASIK and Post-LASIK (one week
and one month) contrast sensitivity was recorded by Pelli-Robson CS charts &
analyzed statistically for both groups.
Results: Contrast Sensitivity at one week post-LASIK was found to be better
in the femtosecond group for which p-value was significant, but when compared
at one month the difference was statistically insignificant.
Conclusion: Contrast sensitivity reverts towards preoperative values faster in
patients undergoing femtosecond assisted LASIK.

Keratokonus Treatment with the Keraflex Procedure - 18 Months
Follow-up
Paulig Sylvia (1)
1. Paulig Eye-Hospital
Objective: Flattening of keratokonus and increase of uncorrected visual acuity.
Methods: Up to now we have treated more than 30 eyes with the Vedera
microwave system to flatten keratoconus corneas. This was followed by
accelerated crosslinking to stabilize the change in corneal curvature.
Results: We will present the topographic data as well as the development of
uncorrected visual acuity over time.
Conclusion: We believe that the keraflex treatment followed by accelerated
crosslinking is a very promising method to flatten keratoconus corneas and to
improve visual acuity. Further research is necessary.

ICLs Long Term Safety and Efficacy
Sarwate Jayant (1)
1. All India Ophthalmological Society
To assess effectiveness of ICL (Starr) as a solution for very high refractive
errors, compound astigmatism and in thin corneas. To assess long term safety
of ICL as phakic IOL Methods- 32 eyes of 17 patients, 15 patients with bilateral
ICL implants and 2 patients with uniocular ICL implants were followed for
minimum 36 and maximum 48 months. Their visual acuity, refraction before and
after surgery, stability of refraction after surgery, IOP measurements, anterior
segment OCT images, slit lamp exam after dilating pupils, were recorded every
6 months. All findings were encouraging.
1. All eyes showed post op increase in VA by one to three lines. The post op
refraction was predictable as shown in the prescription sheet, this remained
constant in all eyes after 36 months
2. There was no evidence of cataract seen after 36 months even at periphery
3. There was no evidence of raised IOP on applanation tonometry
Conclusion: ICL implantation as phakic IOLs in patients in whom lasik was
contraindicatedproved to be a safe and effective method of refractive surgery.
Our findings are consistant with those from other surgeons all over.

Purpose: To evaluate results and complications of intrastromal ring implants in
32 eyes with keratoconus and post lasik keratectasia over a span of 24 months.
Methods: 32 eyes of 20 patients underwent Intrastromal ring implantation with
femtosecond laser. UCVA and BCVA was measured at 1, 3, 6, 12 and 24
months post-op. Refraction, Corneal topography and anterior segment OCT
were done pre-op and post-op.
Results: The mean pre-op UCVA & BCVA was 0.1 and 0.4 and mean post-op
UCVA & BCVA was 0.4 & 0.67 respectively. One case of anterior chamber
perforation was seen on the 1st post-op day and the segments were explanted.
One eye had a corneal melt after 3 months of surgery following a recurrent
inflammatory reaction where the segment had to be removed.
Conclusion: Intrastromal ring segments are useful in management of patients
with keratoconus and post-lasik ectasia where other laser procedures are
contraindicated. Complications need to be identified and treated early.
Removal of segments maybe required in some cases.
