Write this more organized from standard opthal textbooks like khurana or basar and send me not that detailed but just approbation info regarding the orcoedure if possible attach the pictures of the relevant instruments mentioned

I now have all the material I need. I can see from the OCR that your notes cover both SICS/MSICS and phacoemulsification. The Kanski text confirms MSICS steps. Let me also grab the Fig 10.11B (trypan blue staining) image - it should be near line 7008. Let me now compile the full organized response.

Small Incision Cataract Surgery (SICS / MSICS)

Reorganized from Kanski's Clinical Ophthalmology, 10th ed.

Overview

Manual Small-Incision Cataract Surgery (MSICS) is a variant of extracapsular cataract extraction (ECCE). It was developed for high-volume surgical management of dense cataracts, particularly in lower-resource settings. It does not require phacoemulsification technology yet achieves comparable visual outcomes.
"MSICS is faster and avoids the need for expensive technology. Visual rehabilitation is comparable to phacoemulsification."
  • Kanski's Clinical Ophthalmology, 10th ed., p. 336

Context: Cataract Extraction Methods

TechniqueIncisionKey Feature
ICCE (old)~12 mmWhole lens + capsule removed; cryoprobe used
ECCE (conventional)8-10 mmNucleus expressed; sutures required; risk of astigmatism
MSICS~5-7 mmSelf-sealing sclero-corneal tunnel; no sutures needed
Phacoemulsification2.4-2.8 mmUltrasonic fragmentation; most technologically advanced

Pre-operative Preparation

  • Position: Supine on operating table
  • Antisepsis: Povidone-iodine (Betadine) 5% applied to the periocular area
  • Draping & Speculum: Universal (lid) speculum to keep eye open
  • Microscope: Operating microscope; interpupillary distance adjusted for monocular viewing

Anaesthesia

Performed under local anaesthesia (LA). Two main options:

1. Topical / Surface Anaesthesia

  • Agent: Oxybuprocaine (proxymetacaine) eye drops
  • Quick, avoids injection; ~5% of patients still experience intraoperative pain

2. Peribulbar Block (preferred for SICS/MSICS)

  • Injection sites:
    • Upper lateral 1/3 of the orbit
    • Lower medial 2/3 / lateral 1/3 junction
  • Nerves blocked: CN III, V (branches), VI, and VII (orbicularis) - i.e., cranial nerves 3, 5, 6, and 7
  • Provides both akinesia and analgesia
Sub-Tenon's block (blunt cannula injection under Tenon's capsule) is an alternative with fewer complications than sharp needle blocks.

Surgical Steps

Step 1 - Sclero-Corneal Tunnel Incision

A self-sealing scleral tunnel is constructed starting ~2 mm posterior to the limbus:
  • Incision length: ~5-7 mm (allowing nucleus delivery without sutures)
  • Tunnel is beveled to create a valve effect - no sutures required
  • Internal opening into anterior chamber is slightly larger than external opening
Instrument: Crescent knife / scleral tunnel knife (preset blade)
Fig. 10.11A - Scleral tunnel incision (MSICS)
Fig. 10.11A - Scleral tunnel incision - Kanski's, p.336

Step 2 - Side Port Entry

A small paracentesis (side port) is made at approximately 90° from the main incision using a:
  • Instrument: Microvitreoretinal (MVR) blade or keratome (preset to 2.8 mm)
  • Provides entry for second instrument (chopper/vectis)

Step 3 - Anterior Capsulotomy (CCC)

  • Staining: Trypan blue dye injected under viscoelastic to stain the anterior capsule blue (essential for visualization, especially in mature cataracts with absent red reflex)
  • Technique: Continuous curvilinear capsulorhexis (CCC) performed with cystotome or Utrata forceps
  • No capsular tags are permitted - an intact, round rhexis is essential

Fig. 10.11B - Trypan blue staining before capsulorhexis - Kanski's, p.336

Step 4 - Hydrodissection

  • Balanced salt solution (BSS) injected beneath the anterior capsule using a hydrodissection cannula to separate the lens cortex from the capsule
  • Confirmed when the lens rotates freely within the capsular bag
  • Hydrodelineation (injection into the nucleus) can also be performed to separate the nucleus from the epinucleus

Step 5 - Nucleus Expression

The nucleus is delivered en bloc through the tunnel using an irrigating vectis (wire loop with infusion):
  • Viscoelastic is injected into the anterior chamber first to protect the endothelium
  • The vectis slides beneath the nucleus and the nucleus is gently expressed out through the tunnel
  • This is the key distinction from phaco - no fragmentation required
Fig. 10.11C - Expression of the nucleus
Fig. 10.11C - Nucleus expression - Kanski's, p.336

Step 6 - Cortical Aspiration

Residual cortical material is aspirated using a:
  • Simcoe cannula (double-lumen: one lumen irrigates, other aspirates simultaneously)
  • Manual irrigation-aspiration cleans the capsular bag
Fig. 10.11D - Cortical aspiration with Simcoe cannula
Fig. 10.11D - Cortical aspiration - Kanski's, p.336

Step 7 - IOL Implantation

  • Viscoelastic (OVD) re-injected into the capsular bag and anterior chamber
  • Preferred OVDs: sodium hyaluronate (highest molecular weight, best protection) or hydroxymethylcellulose
  • A rigid PMMA IOL (one-piece, designed for MSICS) or foldable IOL implanted into the capsular bag
  • After IOL placement, viscoelastic is thoroughly irrigated out to prevent postoperative IOP rise / secondary glaucoma
  • IOP maintained post-irrigation with Ringer's lactate

Step 8 - Wound Closure

  • The self-sealing tunnel requires no sutures in most cases
  • Wound integrity checked by gentle pressure / cotton swab; anterior chamber must be well-formed
  • Corneal wound sealed by hydration with BSS if needed
